To obtain optimal solutions, Operations Research relies on models. Regarding these models, consider the following statements:
I - Models are representations of reality, and it should be possible to construct a model that takes into account all the complexity of reality as well as the objectives of the study.
II - A mathematical model can be defined as a simplified representation or interpretation of reality, or as the interpretation of a fraction of reality that is relevant to the study.
III - In general, we can construct models that


A) I and II
B) I and III
C) I and IV
D) II and III
E) III and IV
