If all elements of set a are also elements of set b, then set a is a(n) of set b

The correct option is subset.

Step-by-step explanation:

If all elements of set A are also elements of set B, then set A is a(n) subset of set B

According to the definition of subset, A set A is a subset of another set B if all elements of the set A are elements of the set B. In other words, the set A is contained inside the set B. It is denoted by A⊆B.

For example:

A={1,2,3} B={1,2,3,4}

In this example A is a subset of B because all the elements of A  are elements of set B but set B has some extra element. Therefore A is a subset of B

Therefore according to the given explanation the correct option would be subset
