Here working stress applied is equal to stress produced in the prismatic bar.
So, the resultant stress becomes zero and we have
Stress =force/area.
Area = force/stress = force/0 = infinite.
So, the resultant stress becomes zero and we have
Stress =force/area.
Area = force/stress = force/0 = infinite.

The Given Answer is Correct.
Explanation:
as we know that stress= ε*E
or P/A = ε* E
or A = P/ε*E.
Now if working stress equals the stress in the bar then the strain (ε) will be zero, and according to the above equation when strain is zero then Area becomes Infinite.
A = P/0*E
A = Infinite.

I think area has to e infinite when stress is maximum in order to avoid unwanted situation.

Stress = force/area.
According to this, if we increase the stress so the area of section is decreased. So when stress is equal to working stress so the area becomes infinite.
According to this, if we increase the stress so the area of section is decreased. So when stress is equal to working stress so the area becomes infinite.

D should be the correct answer.

Working stress means maximum so the area will be minimum.
