यदि \(A={x:x}\in N\) और (x) अभाज्य है तथा (x<10}) और \(B=\{2,3,5\}\) है तो सही कथन चुनिए।
If \(A={x:x}\in N\) and (x) is prime with (x<10}) and \(B=\{2,3,5\}\) then choose the correct statement.
Explanation opens after your attempt
Correct Answer
B. \(B\subset A\) और \(B\ne A\)\(B\subset A\) and \(B\ne A\)
Concept
\(A=\{2,3,5,7\}\), so (B) is a proper subset. In exams check for missed elements such as (7).
Why this answer is correct
The correct answer is B. \(B\subset A\) और \(B\ne A\) / \(B\subset A\) and \(B\ne A\). \(A=\{2,3,5,7\}\), so (B) is a proper subset. In exams check for missed elements such as (7).
Exam Tip
\(A=\{2,3,5,7\}\) है इसलिए (B) उचित उपसमुच्चय है। परीक्षा में (7) जैसे छूटे तत्व को जांचें।
