Respuesta :
Option C is correct. Scientists use the word theory when a hypothesis is well supported and it unifies a broad range of observations.
A theory can be described simply as a series of ideas or guess that was tabled to explain a concept.
These ideas and concepts are well thought out by scientists to explain a phenomenon and their explanations are based on how they generally view the world. When these ideas which we can also call hypotheses, are well supported based on similar and diverse observations from scientists, we can term them as THEORY.
Hence we can conclude that scientists use the word theory when a hypothesis is well supported and it unifies a broad range of observations.
