यदि \(C=\varnothing\) है, तो \(A\times C\) क्या होगा?
If \(C=\varnothing\), what is \(A\times C\)?
Explanation opens after your attempt
A. \(\varnothing\)
Concept
There is no element in (C) for the second component, so no ordered pair is formed. Cartesian product with an empty set is empty.
Why this answer is correct
The correct answer is A. \(\varnothing\). There is no element in (C) for the second component, so no ordered pair is formed. Cartesian product with an empty set is empty.
Exam Tip
दूसरे घटक के लिए (C) में कोई तत्व नहीं है, इसलिए कोई क्रमित युग्म नहीं बनेगा। खाली समुच्चय के साथ कार्तीय गुणन खाली होता है।
