I'm going with C. Synchronizing the 'foo' method seems like the most logical way to make the entire class thread-safe.

I'm not sure, but I think making setB synchronized could also make the class thread safe.

I agree with Novella, because both foo and sets need to be synchronized to make the class thread safe.

Haha, I bet the correct answer involves the word 'synchronized' in some way. That's the go-to solution for threading issues!

D can't be right, since the question says 'which make class thread safe?' not 'which class is thread safe?'

I think that's not necessary, 'foo' is the critical section.
