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.

Yes, it is right.
Because R = (resitivity*Lenth)/Area.
Area = pi(r1*r1).
Because R = (resitivity*Lenth)/Area.
Area = pi(r1*r1).
