Its so simple in practically if we increase the core diameter of wire then current carrying capacity in increase like example in your home you have used big core wire compare to any low voltage and current electronics devices.

But the resistance should be inversely proportional to current carrying capacity, hence the answer should be A.

Are is how related to current carrying capacity with area of cross section any one explain please clearly or shortly.
