What does a high output in AND gates indicate about the inputs?

A high output in AND gates indicates that all the inputs being fed into the gate are high. In digital electronics, an AND gate functions by outputting a high signal (usually represented as '1') only when all of its inputs are also at a high signal level. If even one input is low (represented as '0'), the output will be low, which means that for the output to be high, each input must individually be high. This characteristic of AND gates directly ties to how logical operations are structured in digital systems, where the desired condition requires all conditions (inputs) to be met (high) for the result (output) to be positive (high). Thus, a high output unequivocally means that all inputs must be high, making option B the correct choice.
