Answer:
The correct option is subset.
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....
