C. (60)

Why this answer is correct
The correct answer is C. (60). This is an ordered selection of (3) from (5), so it is \(^{5}P_{3}\). When there is no repetition and order matters, use permutation.
Exam Tip
यह (5) में से (3) का क्रम सहित चयन है, इसलिए \(^{5}P_{3}\) होगा। बिना पुनरावृत्ति और क्रम हो तो क्रमचय लगाएं।
