Sarah is in a virtual meeting, and her coworker's dog is barking aggressively in the background. Help her politely ask him to mute his audio by selecting the correct verb form.

Excuse me, Bob, but would you mind _____ your microphone while the dog is barking?

The correct answer is muting.

When making a polite request using the phrase "would you mind," the verb that follows must always be in the gerund (-ing) form. "Would you mind to mute" is a common mistake, but it is grammatically incorrect!
