Which one of the following statement is correct? For a 4- input NOR gate, when only two inputs are to be used, the best option for the used input is to—

1. Connect them to the ground
2. Connect them to V_cc
3. Keep them open
4. Connect them to the used inputs

Correct Option: A

The given four inputs NOR gate
When only two inputs are used then rest inputs must be connected to ground, because if any input is connected to Vcc we will get output 0 irrespective of the applied input. However if inputs are open we get floating output. Hence option (A) is the best choice.
