Which statement about a multi-input OR gate is true?

• A. Any input being 1 will produce a 1 output
• B. All inputs must be 1 for a 1 output
• C. The output is 0 whenever any input is 0
• D. The gate outputs a 1 only when all inputs are 1

Answer: (A)

The main idea here is how a multi-input OR gate behaves: it outputs a 1 if at least one input is 1. If any input is 1, the gate goes high, regardless of the other inputs. Only when all inputs are 0 does the output stay 0. That’s why the statement “any input being 1 will produce a 1 output” is the correct description. The other options describe either the behavior of a different gate (an AND gate, which requires all inputs to be 1) or misstate how OR works (for OR, the output is not forced to 0 just because one input is 0; it remains 1 if any other input is 1).
