Correct Answer
C. (8)

The set (A) has (3) distinct elements, so (|\mathcal{P}(A)|=23=8). In exams, treat \(\varnothing\), (1), and ({1}) as different.
Why this answer is correct
The correct answer is C. (8). The set (A) has (3) distinct elements, so (|\mathcal{P}(A)|=23=8). In exams, treat \(\varnothing\), (1), and ({1}) as different.
Exam Tip
समुच्चय (A) में (3) अलग-अलग तत्व हैं, इसलिए (|\mathcal{P}(A)|=23=8)। परीक्षा में \(\varnothing\), (1), और ({1}) को अलग मानें।
