Answer:
C). This is an example of causation

Correlation : It can described the direction of the relation between two or more events or variables.
The conclusion of the experiment is that the plant that received more than two hours of sunlight in each day grew more than the plants that received less than two hours of sunlight in each day.
This is the cause of one event and its effect on the other event.
So option C is correct because sunlight causes plants to grow.
So option C). This is an example of causation.
