Answer:

True

Explanation:

Given are some sets A, B, C, D and Universal set U.

We have


A={1,3,5,7}

When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only

Hence here A' =
{7,5,3,1}=A

This is because whenever we take any element x in A this belongs to A'

Hence
A⊂A'

Similarly any element y in A' also belongs to A

So A⊂A'

Together we have
A=A'

Option d true
