Answer:
Explanation:A) Doing performance benchmarks with the current OS is an unnecessary step in preparing to upgrade a computer to a new OS version. While benchmarking can be a useful tool for assessing a computer's performance, it is not directly related to the upgrade process and does not need to be done prior to the upgrade. The other options are all important steps in preparing for an OS upgrade:
B) It is important to make sure that you have all the device drivers for the new OS before upgrading to ensure that the computer's hardware is supported and functioning properly.
C) Recording custom software settings is important so that you can restore them after the upgrade, ensuring that your software is configured the way you want it.
D) Verifying application compatibility is crucial to ensure that all the software you need to use on the computer will work properly after the upgrade.
