I think the answer is A since all the numbers within the given range in stmt 1 can be expressed as product of two integers each of which is >1

Rephrase the target question as "Is p a non-prime integer?"
Or rephrase it as "Is p a composite integer?"

Statement 1: 31 < p < 37
p=32: composite? Yes
p=33: composite? Yes
p=34: composite? Yes
p=35: composite? Yes
p=36: composite? Yes
We can be certain that p a composite integer.
SUFFICIENT

Statement 2: p is odd
p=7: composite? no
p=9: composite? yes
We cannot be certain that p a composite integer.
NOT SUFFICIENT

Answer = A

Cheers,
Brent

32 33 34 35 36 all are composites (not primes)

hence (A)
