a.
since the resistance of a wire is directly propotional to its area of cross section i.e when the area of cross sectionis doubled the resistance gets halved .... since area also containsradius value in resistance..
b. thin wire has more resistance bcz thin wire has fewer electrons to pass current....
hope this help u
