c. The dependent variable is the plant heights; the independent variable is the room temperature
Explanation:
Here, the effect of room temperature on the height of plants is being studied. The amount of light the plants get is equal the only differentiating factor is the room temperature.
In an experiment to determine the inter relationship between two variables on variable is changed and the variable which changes with respect to the first variable is studied.
The variable which is changed inpendently i.e., it does not change with respect to another variable is called the independent variable.
The variable which changes with respect to the independent variable is called the dependent variable.
Hence, the plant height is the dependent variable and the room temperature is the independent variable.
