..then you can...

The correct answer is C. Hypothesis.

To arrive at this answer, we can break down the options:

A. Theory: A theory is a well-substantiated explanation for a phenomenon or set of observations. In this case, Dr. Muse's idea is not an established or widely accepted explanation. It is a speculative proposition, so it is not considered a theory.

B. Research Question: A research question is an inquiry that guides a study or investigation. It is used to explore a specific problem or issue. The statement provided does not explicitly ask a research question; instead, it presents a claim or proposition.

C. Hypothesis: A hypothesis is a statement that proposes an explanation or prediction for a specific phenomenon. It is based on prior knowledge or observations and is used to guide research and experimentation. Dr. Muse's statement, which suggests that adult teaching can enhance children's ability to reminisce about the past, is an example of a hypothesis.

D. Research Method: A research method refers to the approach or strategy used to gather data in order to answer a research question or test a hypothesis. The statement does not mention a specific method; rather, it introduces an idea or possibility.

Therefore, the correct answer is C. Hypothesis.
