Stephanie is running a 5K race. She wants to keep track of her time and her distance throughout the race. Identify the independent and dependent variable.

A. The independent variable is the time. The dependent variable is the distance of the race.
B. The independent variable is Stephanie's distance. The dependent variable is the time.
C. The independent variable is the time. The dependent variable is Stephanie's distance.
D. The independent variable is the length of the race. The dependent variable is the time.

I think it's D. The independent variable is the length of the race. The dependent variable is the time.

Step-by-step explanation:

Here I'm quoting user kaylaj051903 "because an independent variable is something that is constant and does not change throughout the problem. The dependent variable depends on the independent variable. The race is a 5K race. That will not change. What will change is how long it takes Stephanie to run the 5K race."
