A scientific theory is:

A. a belief held by most of the scientific community.

B. a possible explanation of how things work based only on a guess.

C. an untested explanation of how things work based available evidence.

D. a statement of how things work that has been tested and is in agreement with all data.

Solution

Choice D is correct.

Reason: A scientific theory represents an appropriate explanation and tested justification of occurance of the natural phenomenon that we observe. These explanations are based upon repeated investigations and observations with significantly similar results which decipher the occurence of this phenomenon. The scientific thoeries are never based upon a guess, but they represent a well-fluorished explanation of the occurence of incidences/events with proper scientific investigations, observations and results with statistical significance of high value.
