When (r=n) all objects are being arranged so the count is (n!). In exams treat full arrangement as factorial.
Why this answer is correct
The correct answer is B. सभी (n) objects को क्रम में जमाना / Arranging all (n) objects in order. When (r=n) all objects are being arranged so the count is (n!). In exams treat full arrangement as factorial.
