Which variable goes on the x-axis?

a. the controlled variable

b. the independent variable (manipulated variable)

c. the depenedent variable (responding variable)

The independent variable goes on X-axis.

Option: B

Explanation:

There are two variables in an experiment that are 'independent variable' and 'dependent variable', the 'independent variable' is on 'X-axis' and 'dependent variable' is on 'Y-axis'. The 'independent variable' is the variable which is not depends on the 'dependent variable'. From study we can see that we cannot control the variable is called independent variable.

Let us consider a two variables time and velocity, where time goes on X-axis and velocity goes on Y-axis. It says that time is not a controllable variable but velocity is a controllable variable, thus time goes on X-axis which is the independent variable.
