No, the answer is wrong. The answer is C.

I am 100%. Because in annealing process Hypoeutectoid steel (8% carbon) is headed to 30 degree celsius to 50 degree celsius above the upper critical tempered and cool in the furnace itself by switching off the furnace or the steel is covered either in sand or dry lime and dry ash.
