The truth table for the following logic circuit is :-

Options

A. `{:(A,B,Y),(1,1,1),(1,0,1),(0,1,1),(0,0,1):}`
B. `{:(A,B,Y),(1,1,1),(1,0,0),(0,1,0),(0,0,0):}`
C. `{:(A,B,Y),(1,1,1),(1,0,0),(0,1,0),(0,0,1):}`
D. `{:(A,B,Y),(1,1,0),(1,0,1),(0,1,1),(0,0,0):}`

Answer

A

Explanation

`Y=bar(bar(A)B)+bar(A bar(B))`
`Y = bar(bar(A))+bar(B)+bar(A)+bar(bar(B))`
`Y=A+bar(A)+bar(B)+B`
`Y=1+1=1`
