यदि \(A\subseteq B\) और \(B-A=\emptyset\), तो कौन सा निष्कर्ष सही है?

If \(A\subseteq B\) and \(B-A=\emptyset\), which conclusion is correct?

Explanation opens after your attempt
Correct Answer

A. (A=B)

Step 1

Concept

We have \(A\subseteq B\), and (B) has no element outside (A). Therefore the two sets are equal.

Step 2

Why this answer is correct

The correct answer is A. (A=B). We have \(A\subseteq B\), and (B) has no element outside (A). Therefore the two sets are equal.

Step 3

Exam Tip

\(A\subseteq B\) है और (B) में (A) के बाहर कोई सदस्य नहीं है। इसलिए दोनों बराबर हैं।
