यदि \(A=\{2,4,6,8\}\) और \(B=\{4,8,12\}\) है, तो कौन सा अवयव \(A\cap B\) में है?

If \(A=\{2,4,6,8\}\) and \(B=\{4,8,12\}\), which element is in \(A\cap B\)?

Correct Answer

B. (4)

Step 1

Concept

(4) is in both sets, so it is in \(A\cap B\). For intersection, an element must be in both sets.

Step 2

Why this answer is correct

The correct answer is B. (4). (4) is in both sets, so it is in \(A\cap B\). For intersection, an element must be in both sets.
