Correct Answer
A. (B=C) और (A) (B) का उचित उपसमुच्चय है(B=C) and (A) is a proper subset of (B)
Concept
(B) and (C) have the same elements, and (A) does not contain (4). Check equality and proper subset separately.
Why this answer is correct
The correct answer is A. (B=C) और (A) (B) का उचित उपसमुच्चय है / (B=C) and (A) is a proper subset of (B). (B) and (C) have the same elements, and (A) does not contain (4). Check equality and proper subset separately.
Exam Tip
(B) और (C) में वही अवयव हैं और (A) में (4) नहीं है। समानता और उचित उपसमुच्चय दोनों अलग-अलग जांचें।
