Your options C and D are the same, but it is true that 51 is a composite number.
No. It IS true that every whole number is either prime or composite. But there are numbers that are not whole numbers, such as 2.5, which are neither prime nor composite.
false
false sometimes it contains 2 primes it always comes out to a prime number
Prime numbers can not composite as - Prime number has only 2 factors whereas composite have more than 2

It must have more than two factors.
True

True(Prime factorization is to write a composite number as a product of its prime factors).
No, that's not true.
If you mean factors then it is true because a composite number has more than two factors.
false
False. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. Every multiple of 5 is not a composite number, as 5 itself is a prime number with only two distinct positive divisors, 1 and 5.
