can somebody explain why "timeout from reinforcement " is an independent variable?

An independent variable is the variable that you are manipulating in order to cause the behavior change. If you notice, the question asks for AN independent variable (meaning 1 variable, since this example has 2 independent variables). In this case, the 2 variables that you are manipulating are the time out procedure and the differential reinforcement procedure. Since time out was the only 1 of the 2 in the answers, that makes time out the correct answer.
