C. A researcher may claim that one variable causes another to occur if test results are significant.
Explanation:
Correlation analysis is not meant to show causation between variables but merely to find out if there is a relationship.
While there is a chance of one variable causing another if they are correlated, it is not always the case as there might be another unforeseen variable.
Even if results are significant, a researcher should never claim that one variable can cause another from correlation analysis.
