Explanation opens after your attempt
Correct Answer

C. (16)

Step 1

Concept

First (A'={1,3,5,6}), which has (4) elements. So (\mathcal{P}(A')) has \(2^4=16\) elements.

Step 2

Why this answer is correct

The correct answer is C. (16). First (A'={1,3,5,6}), which has (4) elements. So (\mathcal{P}(A')) has \(2^4=16\) elements.

Step 3

Exam Tip

पहले (A'={1,3,5,6}) है जिसमें (4) तत्व हैं। इसलिए (\mathcal{P}(A')) में \(2^4=16\) तत्व होंगे।

First (A'={2,4,5}), which has (3) elements. So (\mathcal{P}(A')) has \(2^3=8\) elements.

Step 2

Why this answer is correct

The correct answer is C. (8). First (A'={2,4,5}), which has (3) elements. So (\mathcal{P}(A')) has \(2^3=8\) elements.

Step 3

Exam Tip

पहले (A'={2,4,5}) मिलेगा जिसमें (3) तत्व हैं। इसलिए (\mathcal{P}(A')) में \(2^3=8\) तत्व होंगे।
