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.

The question isn't about annealing. It's about "process annealing" aka low-temperature annealing. And in this process metal is heated below low critical temperature. Generally 550-650 degree Celcius. So and is (d) my brother BORAH.

Annealing is not only one process and it contains more.
In that full annealing, process annealing, etc.
So in this question, option D is correct.

Annealing is two types.
1. Full annealing (upper critical temp).
2. Process annealing (LOWER CRITICAL TEMP).
1. Full annealing (upper critical temp).
2. Process annealing (LOWER CRITICAL TEMP).

For annealing process -temp below or close to the LCT, so D option is right.

Answer C is correct because in annealing metal is cooled very slowly in the furnace.

Right @Tejaswini.
If "full annealing" is here, than it will be option 'c'.
If "full annealing" is here, than it will be option 'c'.

No. Answer is wrong because Annealing is done furnace itself only.
