Correct option is : (3) 0
![The output Y of following circuit for given inputs is:](https://www.sarthaks.com/?qa=blob&qa_blobid=9611266860215236694)
\(\mathrm{Y}=\overline{\mathrm{A}} \cdot \mathrm{B} \cdot(\mathrm{A}+\overline{\mathrm{B}}) \)
\(=\overline{\mathrm{A}} \cdot \mathrm{B} \cdot \mathrm{A}+\overline{\mathrm{A}} \cdot \mathrm{B} \cdot \overline{\mathrm{B}}\)
\(=\overline{\mathrm{A}} \cdot \mathrm{A} \cdot \mathrm{B}+\overline{\mathrm{A}} \cdot \mathrm{B} \cdot \overline{\mathrm{B}} \)
\( =0+0=0\)
