The correct answer would be that <u>in science, a theory is well supported by observations and/or experimental data.</u>
<em>Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.</em>
<em>Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.</em>
The correct option is C.
