What is the truth table for an OR gate?

• A OR B = Output, 0 OR 0 = 1, 0 OR 1 = 1, 1 OR 0 = 1, 1 OR 1 = 0

• A OR B = Output, 0 OR 0 = 1, 0 OR 1 = 0, 1 OR 0 = 0, 1 OR 1 = 1

• A OR B = Output, 0 OR 0 = 1, 0 OR 1 = 0, 1 OR 0 = 0, 1 OR 1 = 0

• The truth table for an OR gate is: A OR B = Output, 0 OR 0 = 0, 0 OR 1 = 1, 1 OR 0 = 1, 1 OR 1 = 1
