Explanation / Answer

21)

Definition of subset:A is subset of B if all the elements of A is present.

So D is subset of D as all the elements of set D is present in D

DD is true i.e option (B)

22)

Given sets are {14,15,16} and {14,15,16} let them be sets A and B

here A and B are equal.since A is subset of itself A is also a subset of B

A is not proper set of B because A is equal to B and according to definition of proper set sets shouldn't be equal

so answer is (A)
