Output can refer to which of the following?

• A. production over a specific period of time
• B. yield
• C. energy or power produced by a system or machine
• D. input

Answer: (A)

Output is the result produced by a system, and in everyday and business contexts it most often means the amount produced during a given period. Framing output as production over a specific time interval (for example, units produced per day) captures the typical way we measure how much a process yields. While energy or power produced is a kind of output in physics or engineering, that’s a specialized sense; yield describes how efficiently inputs are turned into outputs, and input is what goes into the system, not the result. So the broad, period-based production measure best represents the common meaning of output.
