Answer: (C)

Using Disk Utility is a crucial step when erasing the system disk for an OSX installation, as it is the built-in macOS application designed specifically for managing disks and storage devices. Disk Utility allows users to format and erase disks securely, ensuring that the chosen formatting scheme is compatible with macOS. It provides various options, such as APFS or macOS Extended formats, which are essential for a successful installation of the operating system. When erasing a system disk, it's important to properly prepare the drive so that it can be formatted correctly and recognized by the macOS installer. Disk Utility also provides features for securely erasing disks, which can be particularly important for safeguarding sensitive information before the installation process begins. While backing up user data is indeed important and should always be done before making significant changes to a system, it is not the step that directly relates to the action of erasing the disk. Running an antivirus scan or installing updates may be useful practices in some contexts but are not essential or relevant to the specific process of preparing a disk for a new OSX installation.

When it comes to prepping your Mac for a fresh OS X installation, there’s one tool that stands out like a neon sign at a dimly lit diner: Disk Utility. You may wonder, why is this such a big deal? Well, let’s break it down.

First things first, let’s talk about what Disk Utility actually does. This built-in macOS application is like your trusty Swiss Army knife for managing disks and storage devices. From formatting to erasing, it’s designed to ensure that whatever drive you’re working with is ready for whatever you throw at it — including a fresh installation. Think of it as the bouncer at a club, making sure only the right formats get through the door to join the exclusive macOS party.

Now, onto the crux of the matter: erasing your system disk. This isn’t just a casual weekend task; it’s a serious business. When you're wiping the slate clean, using Disk Utility is essential. It provides you with the ability to securely erase your disk, ensuring that sensitive information has been done away with completely. After all, who wants their private files lingering around like a ghost haunting their new installation, right?

But wait! Before your fingers even touch the keyboard, don’t forget about backing up your data. Seriously, this step can’t be stressed enough. You wouldn't want to risk losing images of your grandma or those important work documents because you decided to skip it. So, while Disk Utility is the star of the show, your backups are the supporting cast—they make sure the drama doesn’t unfold during the big night.

However, let's clear up some confusion. You might be tempted to think that running an antivirus scan or installing software updates before erasing your disk is a good idea. Sure, those steps are helpful, but they’re not the main act in this performance. The spotlight needs to shine on Disk Utility because it’s the tool that directly handles the erasure process.

In short, if you’re feeling overwhelmed by the prospect of refreshing your Mac, remember: use Disk Utility to erase your system disk. It’s the pathway to a clean and efficient setup that’s primed and ready for the latest macOS. By preparing your drive appropriately, you ensure that the installer recognizes it and can work its magic without a hitch. So go ahead, embrace the process, and get ready to enjoy a brand-new OS X experience.

And you know what? This understanding could just be what sets you apart as an Apple Certified Support Professional in the making. Who knew erasing a disk could feel so liberating? So, roll up your sleeves, grab your Mac, and let’s get this installation journey started!
