Detailed Solution

We have taken two number
p and q are odd number
We know,
Smallest odd prime number =3
Smallest odd composite number = 9
Highest common factor of HCF (3, 9) = 3
Lowest common factor LCM (3, 9) = 9
When we consider odd number p is divided by q2
Thus, p is a factor of q2
Now,
q2×q=q3
q2×q               [it will be factor of q3]
Then,
p is a factor of q3
Therefore, p is divided by q3
Correct option is 1.
