The ones that aren't prime.
Asking a multiple choice question without providing the choices doesn't really seem fair.

What is prime or composite?
Prime numbers r ones that can only be multiplied by itself and 1 to get it and composite is everything else
To find answers to composite numbers fast?
There may not be any fast methods. In fact, composite numbers which are the product of two very large primes are used for public key encryption. This depends on the fact that there is no fast answer to factorising composite numbers.
What are all the composite numbers 1 to 6?
4 & 6 are the only ones
Is it true or false that all numbers with a 0 in the ones' place are composite numbers?
It is true (as long as there are no decimal places after the ones place) because those numbers will always be divisible by 2, 5, and 10. With exception of the number zero which is neither prime nor composite.
Are numbers that have 2 in the ones place composite numbers?
Yes except for 2 on its own which is the only even prime number
Are all numbers that have a 2 in the ones place composite numbers?
Yes, all numbers that have 2 in the one's place are composite numbers. In fact, all even numbers except for 2 itself are composite numbers.
What numbers are not composite?
The ones with less than three factors.
Which numbers are composite numbers?
A composite number is a positive integer, which has a positive divisor other than one or itself.

Are all numbers with a 0 in the ones place a composite numbers?
Yes. All numbers with 0 in the one's column are composite, having at least the factors of 1, 2, 5, and itself. The number 0 is also composite, having all numbers as factors.
What are all the composite numbers 1 to 6?
4 & 6 are the only ones
What are two composite numbers?
There are many composite numbers. The first ones are 4, 6, 8, 9, and 10. Others are 100, 236, 343, 609, and 1115.
Is it true or false that all numbers with a 0 in the ones' place are composite numbers?
It is true (as long as there are no decimal places after the ones place) because those numbers will always be divisible by 2, 5, and 10. With exception of the number zero which is neither prime nor composite.
Are numbers that have 2 in the ones place composite numbers?
Yes except for 2 on its own which is the only even prime number
Why is every natural number with a zero in the ones place composite?
Since the 0 is in the ones place, it will make the whole number even. An even number is composite because it can be divisible by 2 and other numbers too.
Are composite numbers even numbers?
Not all composite numbers are even, but all even numbers except 2 are composite.
