Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

C

Distractor review

Microsoft 365 Business Voice

Incorrect. Upgrading to Business Standard provides desktop versions of Office apps but does not include Audio Conferencing.
