Answer:
The correct answer is option C) "More than one variable is being tested".
Explanation:
One of the basis of scientific experimentation is to test one variable at the time in order to make sure that the response that is being obtained is the result of that variable and not another one that is not taking into account. In this case, the student is making the mistake of assessing two variables at the same time: the use of detergent and placing the plant in the sun or in the shade. At the end of the experiment the student will not know if the response is the effect of the detergent, the exposure to the sun or a combination of both.
