यदि \(A \subseteq U\), तो ((U-A)') किसके बराबर है?

If \(A \subseteq U\), what is ((U-A)') equal to?

Explanation opens after your attempt

Correct Answer

A. (A)

Step 1

(U-A=A'). Therefore ((U-A)'=(A')'=A).

Step 2

The correct answer is A. (A). (U-A=A'). Therefore ((U-A)'=(A')'=A).

Step 3

(U-A=A') होता है। इसलिए ((U-A)'=(A')'=A) है।
