Correct Answer

A. \(A\cup B'\)

Step 1

Concept

By De Morgan's law, (\(A'\cap B\)'=(A')'\cup B'=A\cup B'). When taking complement, \(\cap\) changes to \(\cup\).

Step 2

Why this answer is correct

The correct answer is A. \(A\cup B'\). By De Morgan's law, (\(A'\cap B\)'=(A')'\cup B'=A\cup B'). When taking complement, \(\cap\) changes to \(\cup\).

Step 3

Exam Tip

डी मॉर्गन नियम से (\(A'\cap B\)'=(A')'\cup B'=A\cup B')। पूरक लेते समय \(\cap\) बदलकर \(\cup\) होता है।
