Which option contains a quantitative observation?

Answer and explanation

Correct answer: The candle burned for twelve minutes

A quantitative observation includes a number obtained by counting or measuring, usually together with a unit. It answers questions such as how many, how long, how heavy, or how hot. Descriptions such as sweet, soft, and blue can be useful observations, but they are qualitative because they describe a quality without giving a numerical measurement.

Option D is correct because “twelve minutes” gives a numerical measurement of the candle’s burning time. Minutes are a unit of time, so this observation can be compared with the burning time of another candle under similar conditions. The other options describe taste, texture, and colour. Those observations may be direct, but they are not quantitative unless further measurements are added.
