The correct answer for this question would be option C. If Maritza decided to triangulate her data, the advantage of doing this is that, the results will be more complete. Triangulation is often used to indicate that two (or more) methods are used in a study in order to check the results. The concept of triangulation is borrowed from navigational and land surveying techniques that determine a single point in space with the convergence of measurements taken from two other distinct points. Hope this answers your question.
