Explanation opens after your attempt
A. (11)
Concept
If (A) contains non-prime numbers, then (A') contains prime numbers. There are (11) primes up to (36).
Why this answer is correct
The correct answer is A. (11). If (A) contains non-prime numbers, then (A') contains prime numbers. There are (11) primes up to (36).
Exam Tip
