Question is asking whether n is prime or not.From statement 1:n < 14If n is 2, then 2 and 1 are the only divisors of 2.If n is 4, then 1,2 and 4 are the divisors of 4.Hence, Insufficient.From statement 2:If n = 2n, then 2n < 27.Still Insufficient.Combining both: Again n can be a prime or a non-prime number.Insufficient.E is the answer.
