I'd go with C

n can be 1,2,3,4 for n^3 to lie between 1 and 100

From 1:
n is odd, but there are 2 values 1 and 3 so INSUFF

From 2:
n is 2 or 3 both of which are prime, so INSUFF

From 1 and 2:

n is odd and prime, => n = 3. Hence SUFF

Given
1 < n^3 < 100

or 1 << n < 4

S1: n =2k+1

n = 1, when k =0
n = 3, when k = 1, Not sufficient.

S2: n is prime.. Could be 2 or 3
Not sufficient.

S1 & S2:
n = 3. Sufficient.

i pick E.

k could be 1/2 also
in that case 2 also satisfies n=2k+1 and n is prime.
