If \(A^c=\varnothing\), then (A) is equal to what?
Explanation opens after your attempt
A. (U)universal set
Concept
An empty complement means no element of (U) is outside (A). Therefore (A=U).
Why this answer is correct
The correct answer is A. (U) / universal set. An empty complement means no element of (U) is outside (A). Therefore (A=U).
Exam Tip
पूरक खाली होने का अर्थ है कि (U) का कोई तत्व (A) से बाहर नहीं है। इसलिए (A=U) होगा।
