Question

If A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}, then which of the following statements is false?

1) ∅⊂A
2) B⊆B
3) B⊂A

Answer 1

C should be the correct answer

Answer 2

The correct option is 3.

Explanation:

The given sets are

A = {4, 7, 10, 13, 17}

B = {3, 5, 7, 9}

We know that ∅ is the subset of all sets, therefore ∅⊂A is true.

Each set is the subset of itself, therefore B⊆B is true.

Set B is called a subset of A if and only if all the element of B belong to set A.

Since 3,5,9 ∉ A, therefore B⊄A .

B⊆B is a false statement.

Therefore correct option is 3.
