Which statement is an example of conditional logic?

The statement that serves as an example of conditional logic is one that presents a situation with a clear condition and an action that follows based on whether that condition is met. In this case, the statement "If the signal is green, proceed; else, stop" clearly outlines a scenario where the action (proceeding) is dependent on the condition of the traffic signal being green. If the condition is not met (the signal is not green), the alternative action is taken (stopping). This structure of having a specified condition followed by actions for both outcomes is the essence of conditional logic.

The other options do not demonstrate this kind of conditional reasoning. The remaining statements outline rules or general guidance without tying specific actions to conditions that trigger those actions. They promote best practices or rules but lack the "if-then" format that characterizes conditional logic.
