The truth table for a 2-input NOR gate is as follows:
| A | B | A NOR B | |---|---|---------| | 0 | 0 | 1 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 0 |
To determine which option (A, B, C, or D) corresponds to this truth table, you'd need to compare the options you've been given to the above table. Without the specifics of the options, I can't point you to the correct choice, but this is the standard truth table for a 2-input NOR gate.
