Answer: Option 4. 2, 3, 5, 7, 11, 13
Explanation:
Remember, 1 is neither a prime number nor a composite number, it only has one factor.
So, we can exclude the first and second choice.
The third one has 9. But 9 is not a prime number.
Factor of 9: 1, 3, 9
It has 3 factors
So, this is not prime number and it should be excluded.
The fourth one is a complete list of prime number
Hope this helps!! :)
