Correct Answer

A. ( {3,4} )

Step 1

Concept

First (B-C={3,4}), then the common part with (A) is ({3,4}). Always solve the operation inside brackets first.

Step 2

Why this answer is correct

The correct answer is A. ( {3,4} ). First (B-C={3,4}), then the common part with (A) is ({3,4}). Always solve the operation inside brackets first.

Exam Tip

पहले (B-C={3,4}) है, फिर (A) के साथ सामान्य भाग ({3,4}) मिलता है। कोष्ठक वाली क्रिया हमेशा पहले करें।
