Option A looks like the correct one to me. It uses the $gte and $lte operators to get posts with likes between 100 and 200, inclusive.

I'm not sure, but I think option C might also work because it uses $lt for less than 200.

I agree with Christene, option A makes sense because it includes both 100 and 200 in the range.
