Is "None" an option? All of these answers are wrong.

The number is greater than 2. - 2 is not less than 2.
The number is not divisible by 5. - 2,3,4 are not divisible by 5.
The number is even or less than 12. - 3 is not even.

The number is neuther (assuming neither) prime nor composite. - 4 is not prime. But all numbers are either prime or composite, so was this typed incorrect?

The square root of the number is less than 3 - Root of 10 is 3.16
