Which algebraic expression correctly describes the circuit displayed? Only one answer is correct! (a + b)c\' + ab (ab + c\')(b + c) (a + b)c + bc\' (a + b)c\' + bc\'

Solution

Option a

Totally its an OR gate At last.

Or is combined with 2 AND gates

1 -> 1 Or (a+b) and 1 Not (C\') =>(a+b)c\'

2-> bc

therefore (a+b)c\'+bc
