Answer and explanation
Correct answer: A = B
A prime number is a positive integer greater than 1 with exactly two positive divisors: 1 and itself. The positive primes less than 7 are 2, 3, and 5. The number 1 is not prime, and 7 is excluded because the condition says less than 7, not less than or equal to 7. Therefore A = {2, 3, 5} = B.
