Answer:
The correct option is A) computer simulation
Step-by-step explanation:
Models can be described as as a representation of ideas, events or processes. Models might be mathematical, graphical, visual or computer simulations depending on the type of event being represented.
For studying the motion of clods, a computer simulation will be best because it will make it easier to understand the events related to moving clouds during thunderstorms.
An equation, map or graph cannot be used because neither of them can depict the information for motion of clouds in the atmosphere during a thunderstorm.
