The output Y of the logic circuit shown in figure is best represented as

Options

  1. AA + B . C
  2. BA + B . C
  3. CA + B . C
  4. DA + B ¯ . C ¯

Correct answer

D. A + B ¯ . C ¯

Step-by-step solution

At logic gate- I , the Boolean expression is B . C = Y ' At logic gate- II , the Boolean expression is A +   B . C   = Y ' ' At logic gate- III , the Boolean expression is A + B ¯ . C ¯ = Y
