JavaScript Audio and Video Quiz

I was taking the quiz and noticed that one of the questions requires the wrong answer to be selected to be considered right. The question:

17. What is the purpose of the Media Source Extensions API?

It lets you directly pass a user’s webcam feed to a video element

Enable JavaScript to synchronize multiple audio tracks.

Convert between different media formats.

Add visual effects to video.

I selected “Enable JavaScript to synchronize multiple audio tracks.” And it was marked wrong. The test says the correct answer is “It lets you directly pass a user’s webcam feed to a video element”, however that is the primary function of the Media Capture and Streams API , not MSE right? Or am I mistaken?

Can you link to the url of the quiz please.

This is the quiz I’m talking about:
