Negative reproduction is best described as:

A negative reproduction is an impression—the material records the inverse, or imprint, of the teeth and surrounding tissues. That’s why the best answer is impression: it captures the shape in a way that is the opposite of the actual surfaces. When you later pour gypsum into that impression, you create a positive reproduction, such as a model (or dies for individual teeth). The other terms describe positive replicas or fabrication tools—not the negative imprint itself.
