यदि \(A\subset B\) है, तो किसी समुच्चय (C) के लिए कौन सा कथन सही है?
If \(A\subset B\), which statement is correct for any set (C)?
Explanation opens after your attempt
A. \(A\times C\subset B\times C\)
Concept
If every element of (A) is in (B), then every pair of \(A\times C\) is also in \(B\times C\). In subset questions, focus on the first component.
Why this answer is correct
The correct answer is A. \(A\times C\subset B\times C\). If every element of (A) is in (B), then every pair of \(A\times C\) is also in \(B\times C\). In subset questions, focus on the first component.
Exam Tip
यदि (A) का हर तत्व (B) में है, तो \(A\times C\) का हर युग्म \(B\times C\) में भी होगा। उपसमुच्चय वाले प्रश्न में पहले घटक पर ध्यान दें।
