Which of these is a dependent variable in this demonstration? A. the amount of water in the pan
B. the height of the water in the jar
C. the size of the bottle
D. the number of candles in the jar

B). The height of the water in the jar.

Explanation:

A dependent variable is characterized as the variable that observes the change or effect caused by experimental manipulation in the independent variable. It is the variable that is being tested in the experiment. In the given experiment of the burning candle, 'the height of water in the jar' will rise or drop with manipulation in the independent variable i.e. 'the number of candles.' Since it is affected by the alteration in other variables, it is the dependent variable. Thus, option B is the correct answer.
