Correct Answer
D. (1)
Concept
A power set contains subsets as elements, so (1) alone is not an element. In exams entries of (\mathcal{P}(A)) are sets.
Why this answer is correct
The correct answer is D. (1). A power set contains subsets as elements, so (1) alone is not an element. In exams entries of (\mathcal{P}(A)) are sets.
Exam Tip
घात समुच्चय में उपसमुच्चय तत्व होते हैं इसलिए (1) अकेला तत्व नहीं है। परीक्षा में (\mathcal{P}(A)) में सेट लिखे जाते हैं।
