The correct answer is D. Evan went to the gym with the boys from work.
Explanation
The sentence "He went to the gym with them" is a very ambiguous sentence that does not specify who is meant by the pronouns "he" and "them". So the best option to correct this confusing pronoun antecedent would be to give specificity to these pronouns by giving them proper names or specific characteristics. So the correct answer is D. Evan went to the gym with the boys from work.
Often times, the actual object is much more expensive to create. That's why many designers and engineers create a model to represent their ideas to a group. The model is much cheaper and faster to create, especially if it needs tweaking multiple times. Also, that model can have working parts - you could take it apart to show the inside/cross-section or have interactive sections that allow easier presentation of your idea. Those are things you can't accomplish with an actual object.
