Repeated letters are counted once, so (LEVEL) gives (L,E,V). Repetition is not counted in sets.
Why this answer is correct
The correct answer is A. (A=B). Repeated letters are counted once, so (LEVEL) gives (L,E,V). Repetition is not counted in sets.
Exam Tip
दोहराए गए अक्षर एक बार गिने जाते हैं, इसलिए (LEVEL) से (L,E,V) मिलते हैं। समुच्चय में पुनरावृत्ति नहीं गिनी जाती।
