यदि \(A\setminus B=C\) और \(C\cap B=\varnothing\), तो \(C\subseteq A\) के बारे में क्या कहा जा सकता है?
If \(A\setminus B=C\) and \(C\cap B=\varnothing\), what can be said about \(C\subseteq A\)?

Correct Answer
A. यह सदैव सत्य हैIt is always true
Concept
\(A\setminus B\) is always a subset of (A), so \(C\subseteq A\) is true. A difference cannot contain elements outside the original set.
Why this answer is correct
The correct answer is A. यह सदैव सत्य है / It is always true. \(A\setminus B\) is always a subset of (A), so \(C\subseteq A\) is true. A difference cannot contain elements outside the original set.
Exam Tip
\(A\setminus B\) हमेशा (A) का उपसमुच्चय होता है, इसलिए \(C\subseteq A\) सत्य है। अंतर का परिणाम मूल समुच्चय से बाहर नहीं जा सकता।
