Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

(A) has two distinct elements \(\emptyset\) and \({\emptyset}\). Therefore (n(\mathcal{P}(A))=22=4).

Step 2

Why this answer is correct

The correct answer is B. (4). (A) has two distinct elements \(\emptyset\) and \({\emptyset}\). Therefore (n(\mathcal{P}(A))=22=4).

Step 3

Exam Tip

(A) में दो अलग तत्व \(\emptyset\) और \({\emptyset}\) हैं। इसलिए (n(\mathcal{P}(A))=22=4) है।
