D)four

Question

Quizplus · Accepted Answer

To perform the function of a two-input OR gate using NAND gates, you need three NAND gates. The first two NAND gates act as inverters for each input, and the third NAND gate combines these inverted inputs to produce the OR function output when considering De Morgan's laws.
