यदि \(A=\{1,2,3,4\}\) और \(B=\{2,4\}\), तो कौन सा कथन गलत है?
If \(A=\{1,2,3,4\}\) and \(B=\{2,4\}\), which statement is false?
Explanation opens after your attempt
D. \(A\subset B\)
Concept
(A) is a subset of itself, but it is not a proper subset of itself. Also \(A\subset B\) is false here.
Why this answer is correct
The correct answer is D. \(A\subset B\). (A) is a subset of itself, but it is not a proper subset of itself. Also \(A\subset B\) is false here.
Exam Tip
(A) स्वयं (A) का उपसमुच्चय है, लेकिन अपना उचित उपसमुच्चय नहीं है। इसलिए \(A\subset B\) भी असत्य है।
