Explanation:
A way in which models cannot be useful is: B). being a perfect representation of a situation.
<h3>What is a model?</h3>
A model can be defined as the creation of a physical object either from kits, components or other applicable materials that are acquired by the builder, so as to simulate a phenomenon or process.
This ultimately implies that, a model should be probabilistic in nature rather than being perfect, so as to effectively illustrate or describe the relationship that is existing between an independent variable and the dependent variable.
Generally, some of the ways in which models cannot be useful include the following:
- Building intuition for situations.
- Making predictions that can be verified.
In conclusion, we can infer and logically deduce that way in which models cannot be useful is being a perfect representation of a situation.
