Explanation
The described issue is specific to the video conferencing application, which suggests the application may not have the necessary permissions to use the microphone. Checking and enabling microphone permissions for the application is the correct first step to resolve the issue.
- A. Incorrect.
If the microphone were muted in the operating system's sound settings, it would not work in any application, which is not the case here.
