(C) NOT gate

(D) NOR gate

Answer 2

(D) NOR gate is not a basic logic gate.

Following are the basic types of logic gates:

• NOT gate: This logic gate reverses the input. For example, if the input is 1 the output will be 0.
• OR gate: This logic gate adds the inputs provided to it. If the inputs are A and B, then the output from the OR gate will be A + B
• AND gate: This logic gate multiplies the inputs provided. If the inputs are A and B, then the output from the AND gate will be A.B

NOR gate is basically a combination logic gate. It is combined by the NOT and OR gates. If the inputs of the NOR gate are A and B, the output will be the opposite of A + B.

Therefore, NOR gate is not a basic logic gate.
