Explanation opens after your attempt
A. (24) बैज(24) badges
Concept
The three features are independent so \(4 \times 3 \times 2=24\). While counting designs multiply every independent component.
Why this answer is correct
The correct answer is A. (24) बैज / (24) badges. The three features are independent so \(4 \times 3 \times 2=24\). While counting designs multiply every independent component.
Exam Tip
तीनों विशेषताएं स्वतंत्र हैं इसलिए \(4 \times 3 \times 2=24\)। डिजाइन गिनते समय हर स्वतंत्र घटक को गुणा करें।
