Which Android capability enables a user to obtain root privileges, sideload apps, change or add carriers, and customize the interface of an Android device?

• A. Sideloading
• B. Rooting
• C. Bootloader Security
• D. End of Life (EOL)

Answer: (B)

Gaining root privileges on an Android device is the action of obtaining superuser access, giving you administrative control over the entire system. With this level of access you can modify system files, install apps that require elevated permissions, and replace or customize low-level software. That expanded control makes it possible to sideload apps that need root, flash custom ROMs or modem/firmware, and apply interface/theme modifications that go beyond what standard user access allows. It also enables changing or adding carrier-specific components if you unlock and replace parts of the software stack that the manufacturer or carrier ordinarily restricts.

The other options don’t fit as well. Sideloading refers to installing apps from outside the official store and can be done without root on many devices. Bootloader security deals with protections that prevent unauthorized code from booting and isn’t the capability that enables these customizations itself. End of Life means the device is no longer supported by the vendor and is unrelated to the ability to gain these kinds of control.
