D) duration of study

Answer 1

Answer is option B - Your test score

Reason :-

The dependent variable is a variable whose measurement is being done while testing a change in an experiment .The dependent variable depends on the independent variable in a sentence. Whenever an independent variable is changed, the resulting changes are measured through the change in dependent variable.

In the above example , the test performance is a dependent variable because it is serving as a measure of the participants behaviour while looking at how his sleeping pattern is impacting his test performance scores.
