Correct Answer
A. ({1,2})
Concept
The elements of (A) are written as sets, and ({1,2}) is one of them. The inner (1) and (2) are not directly elements of (A).
Why this answer is correct
The correct answer is A. ({1,2}). The elements of (A) are written as sets, and ({1,2}) is one of them. The inner (1) and (2) are not directly elements of (A).
Exam Tip
(A) में अवयव समुच्चय के रूप में लिखे हैं और ({1,2}) उनमें से एक है। अंदर के (1) और (2) सीधे (A) के अवयव नहीं हैं।
