Explanation:
Prime Number:
- A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
- For example, 2, 3, 5, 7, 11 are prime numbers because they are only divisible by 1 and themselves.
Even Number:
- An even number is a number that is divisible by 2 without leaving a remainder.
- For example, 2, 4, 6, 8 are even numbers because they can be divided by 2.
Combination of Prime and Even:
- Among all the prime numbers, only one prime number is also even, and that number is 2.
- This is because 2 is the only even number that is also a prime number since it is divisible by 1 and itself (2) without any remainder.
Therefore, the correct answer to the question is option C) 2.
