Q11

Incorrect Answer: C

Correction: A, If input B is false, the resulting value coming out of the OR gate will be true (since the value of A is true). Since the value of C is true, the resulting value coming out of the AND gate is true. This result contradicts the statement. Because the value of input A is true, the resulting value coming out of the OR gate must be true. Because the value of input C is true, the resulting value coming out of the AND gate is true. The value of input B did not affect this result.
