An iron-carbon alloy with the carbon content of 0.76 wt.% (eutectoid composition) was held at 800°C for long enough time

[answerhappygod]

An iron-carbon alloy with the carbon content of 0.76 wt.% (eutectoid composition) was held at 800°C for long enough time to acquire a complete and homogeneous austenitic structure and then underwent one of the following 5 heat treatment processes.
A. Quench to room temperature
B. Cool in air to room temperature
C. Cool in furnace to room temperature
D. Quench to room temperature and then reheat to 350°C for 1 hours
E. Quench to room temperature and then reheat to 700°C for 20 hours
Rank the final microstructure of the above heat treated iron-carbon alloy from the highest to the lowest hardness.
