A = {1, 2, 3}  and B = {3, 2, 1}

4∈B is wrong, it should be 4∉B

Both sets are finite. each has 3 elements only

Answer: The answer is (b) A is subset of B.


Step-by-step explanation: Two sets A and B are given as follows -

A = {1, 2, 3}  and  B = {3, 2, 1}.

The given options are

(i) 4 ∈ A. This is not correct, since 4 is a not in the set A.

(ii) A is a subset of B. This option is correct since every element of set A is in set B.

(iii) A is an infinite set. This is also not correct, since A has only 3 elements, so it is a finite set.

(iv) Since option (ii) is correct, so this option is incorrect.

Thus, the correct option is (ii) A is subset of B.
