किस दशा में (P(A')=P(A)) हो सकता है, जबकि पूरक (U) के सापेक्ष लिया गया है?
In which case can (P(A')=P(A)), where complement is taken with respect to (U)?

Correct Answer
C. जब (A=A')When (A=A')
Concept
If power sets are equal, the original sets are equal, so (A'=A) is required. In a finite (U), this means (A) equals its complement.
Why this answer is correct
The correct answer is C. जब (A=A') / When (A=A'). If power sets are equal, the original sets are equal, so (A'=A) is required. In a finite (U), this means (A) equals its complement.
Exam Tip
पावर सेट बराबर हों तो मूल समुच्चय बराबर होते हैं, इसलिए (A'=A) चाहिए। सीमित (U) में यह तभी संभव है जब (A) अपने पूरक के बराबर हो।
