A prime is the number which have two different divisors, one divisor is 1, and other one the number itself. so we can not put 1 in the series of prime numbers as 1 has only one divisor that is 1( itself).

1 2 3 5 7 11 15 is wellknown sequence «number of partitions of n (the partition numbers)»

As mentioned before, answer 13 is incorrect because of 1 is not prime.
You should fix correct answer for this question on 15.
