Explanation opens after your attempt
Correct Answer
A. \(2^{12}\)
Concept
\(A\times A\) has (16) pairs and (4) diagonal pairs are compulsory. The remaining (12) pairs are free, so the number is \(2^{12}\).
Why this answer is correct
The correct answer is A. \(2^{12}\). \(A\times A\) has (16) pairs and (4) diagonal pairs are compulsory. The remaining (12) pairs are free, so the number is \(2^{12}\).
Exam Tip
\(A\times A\) में (16) युग्म हैं और (4) diagonal युग्म अनिवार्य हैं। शेष (12) युग्म स्वतंत्र हैं, इसलिए संख्या \(2^{12}\) है।
