यदि \(A\subset B\) और (n(B)=7) है तो (n(A)) के लिए कौन सा विकल्प असंभव है?
If \(A\subset B\) and (n(B)=7), then which option is impossible for (n(A))?
Explanation opens after your attempt
Correct Answer
D. (7)
Concept
In a proper subset, (A) and (B) cannot be equal, so (n(A)) cannot be (7). A proper subset must have fewer elements here.
Why this answer is correct
The correct answer is D. (7). In a proper subset, (A) and (B) cannot be equal, so (n(A)) cannot be (7). A proper subset must have fewer elements here.
Exam Tip
उचित उपसमुच्चय में (A) और (B) बराबर नहीं हो सकते, इसलिए (n(A)) (7) नहीं होगा। उचित उपसमुच्चय में कम अवयव होने चाहिए।
