Correct Answer

A. (9)

Step 1

Concept

\(9\in U\) and \(9\notin A\), so \(9\in A^c\). Choose the option that is not in (A).

Step 2

Why this answer is correct

The correct answer is A. (9). \(9\in U\) and \(9\notin A\), so \(9\in A^c\). Choose the option that is not in (A).

Step 3

Exam Tip

\(9\in U\) है और \(9\notin A\), इसलिए \(9\in A^c\)। विकल्पों में वही तत्व चुनें जो (A) में न हो।
