Answer:
D). Turbidity, because a decrease in water clarity would indicate and increase in soil erosion.
Explanation:
The last option most aptly describes the direct effect of soil erosion i.e. 'turbidity' which would assist the students in discovering the impact produced by the construction project built on the river. The turbidity is characterized as the 'unit of measuring the transparency of a fluid or the state of being unclear and lesser sediments being disturbed' which <u>causes a significant fall in clarity of the water which signals that there has been a rise in erosion of soil after the construction of the project</u>.

Explanation:
The study that Dr. Keyes wants to do is a study that uses two variables (pets and happiness). Dr. Keyes wishes to prove the cause and effect relationship between these two variables that prove that the greater the amount of pets (causes) people have, the greater the happiness of these people (effect). For this reason, we can say that Dr. Keyes is not doing a correlational study.
This is because, although the correlational study wishes to observe the relationship between two variables, this study cannot be applied to cause and effect relationships.
