Wait, wait, wait... why is there a class A in the code? Is that just a red herring or is it somehow relevant? Ah, who cares, I'll just go with the most straightforward answer, which is B.

I disagree, I believe the answer is A) 4 because there are 4 occurrences of the number 2 in the deque

Hmm, this looks like a simple problem of counting occurrences of a number in a container. I'll go with option B, since 2 appears 3 times in the given array.
