Answer:
Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.
Explanation:
In a controlled experiment, impact of one independent variable is studied on the dependent variable.
Here in this study sunlight is the independent variable while the radish plant is dependent variable.
The researcher wants to study the effect of sunlight on radish plants when they are exposed to it and compare it to the effect created on radish plants that are kept in dark.
