Answer:
Option C, How many planets there are
Explanation:
The model of solar system presented here is a static model which means it can only display the static characteristics. Therefore, this model only presents the number of planets in the solar system. Â
In this model, weight of earth and size of the solar system can be resented through relative scale of weight such a one gram of weight representing 100000 Kg or 1cm representing 1 light year of distance but since no specific detail is given regarding any relative scale , thus option A and D are not the correct choice of answer
Option B is also not a correct choice of answer as speed is a dynamic characteristics and it cannot be represented in a static model.
