यदि \(A\subseteq B\), \(B\subseteq C\) और (A=C) हैं तो (A,B,C) के बारे में कौन सा निष्कर्ष सही है?

If \(A\subseteq B\), \(B\subseteq C\), and (A=C), then which conclusion about (A,B,C) is correct?

Explanation opens after your attempt
Correct Answer

A. (A=B=C)

Step 1

Concept

(B) lies between (A) and (C), and (A=C), so (B) must also be equal to them. In subset chains, check equality conditions carefully.

Step 2

Why this answer is correct

The correct answer is A. (A=B=C). (B) lies between (A) and (C), and (A=C), so (B) must also be equal to them. In subset chains, check equality conditions carefully.

Step 3

Exam Tip

(B) (A) और (C) के बीच है और (A=C) है, इसलिए (B) भी उसी के बराबर होगा। उपसमुच्चय शृंखला में बराबरी की स्थिति ध्यान से देखें।
