Please help answer the attached ques
Square of n between 2 and 100 are: 1, 4, 9, 16, 25, 26, 49, 64, 81

(1) n is even implies there can be many possible answers.
No definite answer; NOT sufficient.


(2) Cube root of n is an integer.
Also n is the square of an integer.
Only 64 has a cube root of 4 (present in the list above), no other integer's cube root is present in the above list; SUFFICIENT.

The correct answer is B.
