यदि \(A\subseteq U\) और (A'=U) है, तो (A) क्या होगा?

If \(A\subseteq U\) and (A'=U), what is (A)?

Explanation opens after your attempt
Correct Answer

B. \(\varnothing\)

Step 1

Concept

If the complement of (A) is the whole (U), then (A) cannot contain any element. Hence \(A=\varnothing\).

Step 2

Why this answer is correct

The correct answer is B. \(\varnothing\). If the complement of (A) is the whole (U), then (A) cannot contain any element. Hence \(A=\varnothing\).

Step 3

Exam Tip

यदि (A) का पूरक पूरा (U) है, तो (A) में कोई तत्व नहीं हो सकता। इसलिए \(A=\varnothing\) है।
