The circuit shown in the following figure realizes the function
(A) ( ( A + B )’ + C ) ( D’ E’ )
(B) ( ( A + B)’ + C)(D E’ )
(C) ( A + ( B + C )’) ( D’E )
(D) (A + B + C’ )( D’ E’)
Explanation: The expression can be simplified by using the DeMorgan’s theorem i.e. (A + B)’ = A’. B’ or ( A.B)’ = (A’ + B’)
(((A + B)' + C)' + ((D + E)')')' ((A + B)' + C) ((D + E)' ((A + B)' + C) (D' E')
Option (B) is correct.
