Explanation:

Field study involves direct - observation and collection of data in the natural environment. Since Matthew wants to study fossils in the rock layers at the Grand Canyon, a field study would allow him to directly access and analyze the fossils in their natural setting. Interviews are for gathering information from people, case studies focus on in - depth analysis of a particular case, and controlled experimentation is for testing hypotheses under controlled conditions, none of which are as suitable as field study for this task.

Answer:

C. field study
