|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.

|Anyone please explain this.|

|D should be the correct answer.|
|Deepak Kumar said: (Feb 20, 2018)|
|Working stress means maximum so the area will be minimum.|
|Skm said: (May 12, 2018)|
|Option D is correct.|
|Satya said: (May 25, 2018)|
|Option D is correct I think.|

|Freely prismatic bar stress is equal zero. So area is infinite.|
|Hemraj Basnet said: (Feb 9, 2019)|
|Consider S = stress.
Then partial derivative of stress with respect area.
dS/dA=pd(A power minus 1)/dA,

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

|Minumum is correct one.|

|Yes, you are right, Thanks @Jay Brahmabhatt.|
