Answer:
The correct answer is One is a factor of every whole number since every number is divisible by itself.
Explanation:
A factor is that number that divides another number evenly, with no remainder. That is why the number 1 is a factor of every whole number since every number is divisible by itself.
On the other hand, the number 1 is not a prime number since it cannot be divided by two factors.
It is also not a composite number since it does not have two smaller positive integers.
Therefore, the correct answer is One is a factor of every whole number since every number is divisible by itself.
