यदि \(A\subset B\) और \(B\subset C\) हैं, तो (A) और (C) के बारे में कौन सा कथन सही है?
If \(A\subset B\) and \(B\subset C\), which statement about (A) and (C) is correct?
Explanation opens after your attempt
A. \(A\subset C\)
Concept
With two proper inclusions, (C) must have more than (A). Hence (A) is a proper subset of (C).
Why this answer is correct
The correct answer is A. \(A\subset C\). With two proper inclusions, (C) must have more than (A). Hence (A) is a proper subset of (C).
Exam Tip
दो उचित बढ़ाव होने से (C) में (A) से अधिक सदस्य जरूर होंगे। इसलिए (A) (C) का उचित उपसमुच्चय है।
