Which statement is true regarding the pump shown in the diagram?

The assertion that only one pump will pump water is supported by the understanding of pump functionality and design. In many cases, the operational condition of a pump can be influenced by various factors including its mechanical integrity, type of pump, and the system it is connected to. If the diagram indicates that one specific pump is operating, possibly because it is correctly primed, powered, or configured, while the others exhibit signs of malfunction or improper conditions, this would validate the assertion that only one is functional.

Understanding pump operations typically includes checking for wear and tear, ensuring proper connections, and making sure that each pump is set up for the specific medium it is intended to move. The other options could misrepresent the situation if they suggest all pumps are equally functional or that no pump operates, which could mislead users about the condition and readiness of the equipment at a glance. It’s essential to analyze conditions visually or through diagnostics to accurately determine functionality.
