I’m leaning towards B as well, but I feel like I need to double-check what the other options mean.

I’m a bit confused. I thought amplifiers could also mix signals, but maybe that’s a different type of device?

I remember practicing a question like this, and I believe the answer is B. It definitely has to do with driving speakers.

I think an amplifier is related to increasing power, but I’m not completely sure if it’s just for audio signals or if it can do more.
