Which HTML element is used to display a scalar measurement within a range?

• A. Meter
• B. Progress
• C. Output
• D. Span

Answer: (A)

Think of a gauge that shows where a value sits within a defined range. The meter element is designed for that purpose: it displays a scalar measurement with a known minimum and maximum, letting users see how the current value falls inside that interval. You set min and max to define the scale and value to show the current measurement. Optional attributes like low, high, and optimum help highlight zones (for example, safe, warning, or target ranges). This is why it’s the best choice here: it communicates a measured quantity within a range, not a progress toward a goal or the result of a calculation. For comparison, a progress element represents completion toward a task, not a value within a scale. Output is the result of a calculation or action, not a gauge. Span is just a generic container with no semantics for measurements. Example: <meter value="65" min="0" max="100" low="30" high="70" optimum="90">65%</meter> This shows a gauge at 65% of the 0–100 range, with zones indicated by the extra attributes.
