These are some ways how scientists and engineers develop, use and refine models.
1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.
2. Reason. Next, they need to answer the questions brought from their brainstorming. They need to be able to reason out.
3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.

Explanation:
B. liquid! Becuase its Seperational atoms have a Huge Attraction within Heated Atoms..from the Sunlight It then sweats..It starts too Evaperate then later by time it Rains.. Etc "Water Cycle" correct me if im Wrong..
