Why this answer is correct
The correct answer is A. \(5!\cdot3!\). The block of three people and the remaining (5) people form (6) circular objects, giving (5!) arrangements. In exams use one less factorial for circular block objects.
Exam Tip
तीन लोगों का one block और बाकी (5) people मिलकर (6) circular objects बनाते हैं, इसलिए (5!) arrangements हैं। परीक्षा में circular block count में objects minus one factorial लें।
