To solve this problem, we'll check each number to determine if it's a prime:
- Number 6: Greater than 1 but divisible by 2 and 3. Not prime.
- Number 4: Greater than 1 but divisible by 2. Not prime.
- Number 8: Greater than 1 but divisible by 2 and 4. Not prime.
- Number 2: Greater than 1 and not divisible by any other numbers except 1 and itself. It is prime.
Therefore, the prime number from the options is 2.
