Answer:
The correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
Explanation:
In this three plants in three different conditions shows three different outcomes so their is sufficient replication to draw a conclusion. The wavelength of the light affects the growth of the plant. UV light has very low wavelengths below 400 nm than the photons required similarly Infrared light has higher wavelengths that is low energy light, UV can cause wilting and leaf burn.
So, the wavelengths of the light and growth of plant are related and this experiment only wavelengths of the lights are changed.
Thus, the correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
