A nuisance variable is a variable that affects the dependent variable but is not of interest to the research question. It varies randomly and equally across conditions. On the other hand, a confounded variable is a variable that varies with the independent variable and affects the dependent variable, making it difficult to determine which variable is responsible for the results. Therefore, the best choice is D as it correctly identifies the confounded variable as varying with the independent variable.
