Which of the following is INCORRECT, as per a 2-input OR gate truth table?
  • AIf input A=1, B=0, then output Y=1.
  • BIf input A=0, B=0, then output Y=1.
  • CIf input A=1, B=1, then output Y=1.
  • DIf input A=0 , B=1, then output Y=1.
Correct answer: B

Explanation

An OR gate gives output 1 when at least one input is 1. For inputs 0 and 0 the output is 0, so the statement "output Y = 1" is incorrect.
