Answer 1

The best option and the one who explains itself better is the first option Megabits per second; because the independent quantity is time in seconds and dependent quantity is amount of data in megabits. In this case the dependent variable is the amount of data in megabits, something you can control, but time in seconds is indeed the independent variable.
