Answer:

D. independent variable.

Explanation:

According to my research on different experimental terminology, I can say that based on the information provided within the question the difference in lighting in this study is an independent variable. This is because the focus of the study seems to be whether a certain diet affects the rats abilities and speed in finishing the maze. The results for this study do not depend on the lighting because rats can navigate in the dark just as fast as in the dark because of their whiskers.
