What is the most likely reason why scientists change a model?

A. The public wants to understand a concept more easily

B. Students need illustrated models in a study guide

C. New discoveries makes the current model inaccurate

D. Current models may be uninteresting

A doesn't change the model, that's what google's for, B can be easily used with the current model, and D is ridiculous.

The model of, for example, the atom, has changed over the years with multiple experiment sand multiple models. There was plum pudding, for example, with protons and electrons scattered throughout, until Rutherford's experiments (a new discovery) changed that because he found a dense nucleus.
