यदि \(A=\varnothing\) और सार्वत्रिक समुच्चय (U) है, तो (A') किसके बराबर होगा?
If \(A=\varnothing\) and the universal set is (U), what is (A') equal to?
Explanation opens after your attempt
B. (U)
Concept
The empty set has no elements, so all elements of (U) lie in its complement. Hence \(\varnothing'=U\).
Why this answer is correct
The correct answer is B. (U). The empty set has no elements, so all elements of (U) lie in its complement. Hence \(\varnothing'=U\).
Exam Tip
रिक्त समुच्चय में कोई तत्व नहीं होता, इसलिए (U) के सभी तत्व उसके पूरक में आते हैं। अतः \(\varnothing'=U\)।
