If \(A^{c}=\varnothing\), which statement about (A) is correct?
Explanation opens after your attempt
B. (A=U)
Concept
If the complement is empty, then (A) covers the whole (U). Therefore, (A=U).
Why this answer is correct
The correct answer is B. (A=U). If the complement is empty, then (A) covers the whole (U). Therefore, (A=U).
Exam Tip
यदि पूरक खाली है, तो (A) ने पूरे (U) को कवर कर लिया है। इसलिए (A=U) होगा।
