Variables are the parameters in the experimental sciences used to determine the results. The bounce height of the ball is a dependent variable. Thus, option a is correct.
A dependent variable is a type of variable and as the name suggests is a value that is estimated and determined by the independent variable or some other factors.
The dependent variable is the parameters that have needed to be estimated or tested in the experiment and are compared to the data that resulted from the independent variable.
The bounce height of the ball is a dependent variable as it depends on how much height and energy the ball will acquire if they are dropped from a certain height.
Therefore, bounce height is a dependent variable.
