I believe it provides details on which DMA channels are active, but I could be mixing it up with another command.

Okay, this seems straightforward. The command is clearly about DMA, so the answer must be which DMA channels are in use. I'll select option B.

The question is asking what the command `cat /proc/dma` will show, so I'm guessing it's related to DMA configuration on the system. I'll try option B.

I'm just hoping the exam doesn't ask me to explain what DMA stands for. That would be a real 'direct memory access' moment for me. *winks*
