The correct option is D 2
The least prime factor of p is 5, so p is not divisible by 2.
⇒ p is an odd number
The least prime factor of q is 11, so q is not divisible by 2.
⇒ q is an odd number
The sum of two odd numbers is divisible by 2.
Hence, the least prime factor of (p + q) is 2.
Hence, the correct answer is option (d).
