Correct answer: {2}
Explanation:
A prime number is a number that has only two distinct positive divisors: 1 and itself.
An even number is a number that is divisible by 2.
2 is the only number that is both even and prime because:
- It is divisible only by 1 and 2
- It is even
Hence, the only even prime number is 2, and the set is {2}.
