Explanation:
The experimental and control group differ by <u>only one factor</u> for a scientist, and that is the independent variable.
<em>A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.</em>
The correct option is, therefore, C.
