The answer is B. On the contrary, she loves to eat frogs' legs.
Reason, in A there shouldn't be a comma after missing. I doesn't make sense, the comma should be after By the way, I found your missing leather gloves.
Reason, in C. there should be a comma after pen. This pen, for instance, has green ink.
Reason, in D. there should be a comma after clock. It's about six o'clock, I guess.
Hope this helps. :)
