Which statement is true about 513? A. It is a prime number. B. It is a composite number. C. It is a whole number that is neither prime nor composite. D. It is not a whole number.

Yes i would agree with B

A isn't true because 513 is at least divisible by 3, so it's not a prime number.

C isn't true because all whole numbers are either prime or composite.

D isn't true because it is neither a imaginary number, fraction, decimal, or unreal number, so therefore it must be a whole number.

B is true, because it is able to be divided by numbers other than one and itself.
