In an OR logic table, the output is 1 if at least one of the inputs (first or second) is 1. The only situation where the output is 0 is when both inputs are 0.
Here are the correct scenarios for an OR logic table:
- first input: 0, second input: 0, output: 0
- first input: 0, second input: 1, output: 1
- first input: 1, second input: 0, output: 1
- first input: 1, second input: 1, output: 1
Given the options you listed, only the following row is valid for an OR logic table:
- first input: 0, second input: 0, output: 0
The other rows given do not correctly represent the OR logic functionality since OR should provide output of 1 when at least one input is 1.
