Correct Answer
A. ({1,2}) और ({3})({1,2}) and ({3})
Concept
(1) and (2) are related to each other, while (3) is related only to itself. Hence the classes are ({1,2}) and ({3}).
Why this answer is correct
The correct answer is A. ({1,2}) और ({3}) / ({1,2}) and ({3}). (1) and (2) are related to each other, while (3) is related only to itself. Hence the classes are ({1,2}) and ({3}).
