If A ⊂ B, then which of the following describes the relationship between A and B?
Set A can have the same number of elements as set B.
Set B may have fewer elements than set A.
The intersection of sets A and B must be the empty set.
Set B may have more elements than A does.

Solution:

Let us assume set A and set B such that A ⊂ B

Set A= {1,2} and B ={1,2,3}

Here, subset means every element in set A should be in set B. If A ⊂ B, we can say that all the elements in A are present in B.

There are chances that both sets can be equal. So, clearly option A maybe always true.

Option B, option C don’t support our assumption and condition.

Hence, set B may have more elements than set A which is always true.

If A ⊂ B, then which of the following describes the relationship between A and B?
Set A can have the same number of elements as set B.
Set B may have fewer elements than set A.
The intersection of sets A and B must be the empty set.
Set B may have more elements than A does.

Summary:

If A ⊂ B, then the relationship between A and B can be described as set B may have more elements than set A.
