The dependent variable is generally the variable which is expressed as a function of the independent variable. Traditionally, the dependent variable is alone on the left side of the equality and on the right side is some function of the independent variable. Given this, what do you think the answer to the question is?

Correct. The value of h depends on the value of t.
