The output Y of the logic circuit given below is 
- A \(\bar{A}+B\)
- B \(\bar{A}\)
- C \(\overline{(\overline A+B)} \cdot \bar{A}\)
- D \(\overline{(\overline A+B)} \cdot A\)
Answer & Solution
Correct Answer
(B) \(\bar{A}\)
Step-by-step Solution
Detailed explanation
By absorption laws \[ Y=\bar{A}+\bar{A} \cdot B \] or \(\quad Y=(\bar{A} \cdot B)+\bar{A}=\bar{A} \cdot(B+1)=\bar{A} \cdot 1=\bar{A}\)
