Why this answer is correct
The correct answer is A. क्योंकि समान अक्षरों की आपसी अदला-बदली नई व्यवस्था नहीं बनाती / Because interchanging identical letters does not make a new arrangement. Internal arrangements of identical letters are not visibly different. In exams identify repeated letters and divide by their factorials.
