यदि (A\setminus\(B\cap C\)=\varnothing), तो कौन सा कथन अवश्य सत्य है?
If (A\setminus\(B\cap C\)=\varnothing), which statement must be true?
Explanation opens after your attempt
A. \(A\subseteq B\cap C\)
Concept
Nothing remains after removing \(B\cap C\) from (A), so all of (A) lies inside \(B\cap C\). Identify subset relations from empty difference.
Why this answer is correct
The correct answer is A. \(A\subseteq B\cap C\). Nothing remains after removing \(B\cap C\) from (A), so all of (A) lies inside \(B\cap C\). Identify subset relations from empty difference.
Exam Tip
(A) से \(B\cap C\) हटाने पर कुछ नहीं बचा, इसका अर्थ है (A) पूरा \(B\cap C\) में है। शून्य अंतर से उपसमुच्चय पहचानें।
