Answer 2

C). A descriptive investigation usually does not involve much data collection to support a hypothesis.

Step-by-step explanation:

The limitation of a descriptive investigation is that 'it lacks sufficient data to support the proposition.' A descriptive investigation does not test the validity of a truth or distinct methods of growing it or to make comparisons between them. It rather focuses only on describing in-depth instead of practically examining the validity of the fact and using it to supporting the claim made in the hypothesis, unlike an experimental investigation. Thus, option C is the correct answer.
