The question can be rephrased as "Is k a perfect square? "

A number is said to be a perfect square where all the prime factors have even exponents.

from statement 1, it is said that 4 which is 2^2 is the factor of K. But it didn't say if it is the only factor. So we don't what other factors are and what their exponents are? So insufficient.

From statement 2, it is said that k is having 4 distinct prime factors. But nothing was mentioned abt the exponents. So insufficient.

Together also we don't whether the exponents of the prime factors are even or not. Hence both the clues are insufficient.

IMO E.
