Correct Answer
A. \(\varnothing\)
Concept
No element belongs to both (A) and (A'), so the intersection is empty. This rule applies to every set.
Why this answer is correct
The correct answer is A. \(\varnothing\). No element belongs to both (A) and (A'), so the intersection is empty. This rule applies to every set.
Exam Tip
कोई अवयव (A) और (A') दोनों में नहीं होता, इसलिए प्रतिच्छेद खाली है। यह नियम हर समुच्चय पर लागू होता है।
