C looks tempting, but it won't replace all occurrences.

I thought it was A at first, but B makes more sense.

Wait, why does B have a 'g'? Is that really necessary?

I thought the command needed to end with a 'g' for it to change all occurrences, but I can't recall if that's in option B or not.

I practiced a similar question, and I feel like the correct answer should have the 's' and 'g' together. So, B seems right to me.

I'm not entirely sure, but I remember something about using slashes in sed commands. Was it option A?

I think the command needs to include a 'g' for global replacement, so maybe it's option B?

I think the answer is B. The 's/bob/Bob/g' syntax looks right to me for replacing all instances of 'bob' with 'Bob' in the file 'data'.

I'm a bit unsure about this one. I know sed is powerful for text processing, but I'm not super familiar with the different syntax options. I'll have to review my notes before deciding.

The key here is the 'g' flag in the sed command, which stands for 'global' and ensures all occurrences are replaced, not just the first one. I'd go with B.

Hmm, I'm a bit confused on this one. I know sed is used for text manipulation, but I'm not totally sure about the specific syntax. I'll have to think this through carefully.

I'm pretty sure the answer is B. The 's/bob/Bob/g' syntax in sed is used to replace all occurrences of 'bob' with 'Bob'.
