Correct Answer
B. (A=B=C)
Concept
Mutual subset inclusion makes all elements the same so (A=B=C). In exams prove equality by two way inclusion.
Why this answer is correct

Exam Tip
परस्पर उपसमुच्चय संबंध से हर समुच्चय के तत्व समान हो जाते हैं इसलिए (A=B=C)। परीक्षा में द्विपक्षीय समावेशन से बराबरी सिद्ध करें।
