How does an OR gate differ from an AND gate?

An OR gate operates on the principle that its output will be high (or true) if at least one of its inputs is high (or true). This means that even if only one of the inputs is activated, the OR gate will still produce a high output. This functionality is distinct from that of an AND gate, where all inputs must be high in order for the output to be high.

The correct answer illustrates this fundamental behavior of the OR gate, emphasizing its flexibility in producing a high output. The ability to activate the output with just one high input makes OR gates particularly useful in various electronic circuits and logical operations, where multiple conditions can lead to a positive result.

In contrast to the other options, which imply more restrictive conditions or different functionalities, this choice accurately captures the defining feature of an OR gate.
