Option (C).

Models help scientists visualize things they can't see

Explanation:

Since a long time models have been used by scientists to study about various things and phenomenons. A model helps the scientist community understand things that they cannot actually see or fathom. It can be thought of as a thinking tool, to help form explanations. It represents physical and touchable visualization of the theory rather than imaginative.

Models are useful simplifications to aid understanding. It can then be used to explain further phenomena and to make predictions of future behavior. Hence, models are very helpful for scientists in various studies.
