Which of the following statements are true?

i. For any set A, A is a proper subset of A

ii. For any set A, Φ is a subset of A

iii. For any set A, A is a subset of A

i. For any set A, A is a proper subset of A

No set is proper subset of itself

(or)

Let us say A = {1,2,3,4}

For a proper subset n(A) ≠ n(A)

But here n(A) = n(A)

So, it is not proper subset to itself.

ii. For any set A, Φ is a subset of A

it is a property of null set, that it is subset to any other set except to itself (Φ)

So, it is true.

iii. For any set A, A is a subset of A

It is also property of subset that it is subset to itself and null set (Φ)

So, it is also true

Since (ii) & (iii) is correct statement. option (B) is the correct answer.
