In an AND truth table, what is the output when A = 1 and B = 1?

• A. False
• B. Undefined
• C. True
• D. Cannot be determined

Answer: (C)

An AND operation outputs true only when both inputs are true. In binary terms, 1 AND 1 equals 1. Since A is 1 and B is 1, the output is true. The other possibilities don’t apply here because an AND gate doesn’t produce false or undefined if both inputs are true.
