Identify the property or theorem which justifies the statement. 7 × 3 is an integer

A) Associative property
B) Inverse property
C) Closure property
D) Multiplicative identity

The property or theorem that justifies the statement "7 × 3 is an integer" is the Closure property.

To explain how the Closure property applies here, we need to understand what the Closure property is. The Closure property states that if you perform a certain operation on two elements of a certain set, the result will also be an element of that set.

In this case, we are performing the multiplication operation on the numbers 7 and 3. Both 7 and 3 are integers, and since multiplication of two integers always results in another integer, the Closure property applies. Therefore, we can conclude that the product of 7 and 3 is indeed an integer.

So, the correct answer is C) Closure property.
