Which of the following is NOT an implication statement?

A statement that is NOT an implication typically asserts a condition or fact without suggesting a consequence based on that condition. In this context, the other statements (A, B, and D) imply a course of action or a consequence that should be considered: replacing oversized fuses to reduce fire hazards, changing receptacle polarity to prevent electrical shock, and noting that the absence of roof drains may negatively impact the lifespan of the roof membrane.

The statement regarding the faucet below the rim of the tub simply identifies a condition—denoting a cross connection—without suggesting further implications or actions that arise from that identification. It merely states a fact about plumbing without tying it to consequences or required actions, making it distinct from the implication-laden statements provided in the other options.
