I practiced a similar question, and I think it was also about 24 bits for the vendor ID. So, B seems right to me.

I feel like I studied this, but I can't recall if it's 16 or 24 bits for the vendor part. It’s confusing!

I remember something about MAC addresses having 24 bits for the OUI, so I'm leaning towards option B.

I think the first part is about the vendor identifier, so it might be 24 bits, but I'm not completely sure.
