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.

It can cause a chain reaction. Every cause has an effect.
Example: Someone throws a cigarette out their window, causing a grass fire
Scenario A: A prairie dog population was killed in the grassfire simply because they had no time to escape.
Scenario B: The grasshoppers don't have grass to eat, so the prairie dogs don't have meat to survive because the grasshoppers are starving. Either way, the person who threw the cigarette caused a decrease in the population.
