A) a scientific theory or principle

B) an experiment

C) experimental results

D) descriptive researclh

E) a scientific model

A) a scientific theory or principle

Explanation:

A Theory or principle has to explain different observations for a specific phenomenon. Theories are tested in base of new data to see if they can fit with all the new variations. They gain more acceptance in the scientific world if they predict in a correct way the result of many observations.

For example the uncertainty principle which state that the position and the momentum of a particle can not be known at the same time. Many experiments that aim to test the Uncertainty principle demonstrated this property, but tests are currently being done with other variations to see if the principle still fits with them.
