A) the number of trials it takes to run the maze without making any errors
B) the trials in which the supplement is used
C) the presence or absence of the supplement in the animal's diet
D) the two different mazes used
Independent Variable

Final Answer :
C
Explanation :
The independent variable is the one that is being manipulated or changed by the researchers in the study. In this case, the researchers are manipulating the presence or absence of the supplement in the animal's diet, which is the independent variable. The number of trials it takes to run the maze without making any errors is the dependent variable that is being measured as a result of the independent variable. The trials in which the supplement is used and the two different mazes used are not the independent variables in this study.
