unfortunately i took pq as number like 32 in which p represents number 3 and q is 2 , considering this way the answer is c the question is little bit vague because p*q is sometimes different from pq

Here, you need to answer the question “is pq an odd integer?”. In statement two p+q is an odd integer, you will get an odd integer only when adding one odd and one even numbers. ( odd+odd=even, Even + even = even, Odd + even = odd) Therefore, when you multiplies an odd number with an even number, always it would be an even number. So we can answer the question ‘is pq an odd integer?’ using statement 2 alone as ‘no, it would be an even number’ ( statement one not required).

because all prime numbers(except for 2) are odd numbers...so s1 is not required.
