Correct Answer
B. (3)
Concept
The valid selections are \(A^3N^2\), \(BA^2N^2\), and \(BA^3N\), so the total is (3). In small repetition questions, list valid distributions directly.
Why this answer is correct
The correct answer is B. (3). The valid selections are \(A^3N^2\), \(BA^2N^2\), and \(BA^3N\), so the total is (3). In small repetition questions, list valid distributions directly.
Exam Tip
वैध चयन \(A^3N^2\), \(BA^2N^2\), और \(BA^3N\) हैं, इसलिए कुल (3) हैं। छोटे बहुलता प्रश्नों में वैध वितरण सीधे लिखें।
