Explanation:

A physical model is a tangible representation of an object or system. The student used colored balls and sticks to create a three - dimensional, hands - on model of ammonia, which is a physical object. It's not a miniature in the context of this question as it's not about size comparison, not a mathematical model as it doesn't involve equations or numerical relationships, and not a conceptual model which is more abstract and idea - based.

Answer:

D. Physical
