Correct option is B
Explanation:
· Universal Logic Gates: A universal gate is one that can be used to create any other type of gate (AND, OR, NOT, etc.) and, therefore, can implement any Boolean function.
· NOR Gate: The NOR gate is a universal gate because you can construct all other logic gates using just NOR gates. For example:
· NOT gate can be made by connecting both inputs of a NOR gate to the same input.
· AND and OR gates can also be constructed using combinations of NOR gates.
