When Lexie purchased a new laptop, it came with a 30-day trial copy of Microsoft Office.After paying for the full version, what else must Lexie do to continue using the software?

A) Activate the software.
B) Register the software.
C) Install the software.
D) Uninstall the software.

After purchasing the full version of Microsoft Office, Lexie must activate the software to continue using it. This involves entering a product key or code provided with the purchase to unlock the full version. Registering the software and installing it are typically done during the initial setup process and would not need to be repeated after purchasing the full version. Uninstalling the software would remove it completely from the computer and prevent Lexie from using it at all.
