B) False. The question is a bit confusing, but I think the correct answer is that the read request is first hit in the cache, not the other way around.
A) True. This seems like the right answer to me. The question could be worded better, but I think it's saying that the write request is written to the cache, and the read request is first checked in the cache.
B) False. The question is confusing, but I think the correct answer is that the read request is first hit in the cache, and if it's not hit, it's read from the disk.
I think I've got a handle on this. The key is recognizing that the read request is first checked in the index, and if it's not found there, it's read from the cache. I'll double-check my understanding before answering.
