In order to be accepted, a scientific theory must be
A
widely tested and supported by extensive data
B
based on the results of a single experiment
C
controversial and cause debate
D
in line with all previous historical ideas
Explanation: 

Detailed explanation-1: -Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected. The longer the central elements of a theory hold-the more observations it predicts, the more tests it passes, the more facts it explains-the stronger the theory.

Detailed explanation-2: -A scientific theory is a hypothesis that has been extensively tested, evaluated by the scientific community, and is strongly supported. Theories often describe a large set of observations, and provide a cohesive explanation for those observations.

Detailed explanation-3: -A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Examples of theories in physical science include Dalton’s atomic theory, Einstein’s theory of gravity, and the kinetic theory of matter.

Detailed explanation-4: -To be accepted by the scientific community, a theory (in the scientific sense of the word) must be strongly supported by many different lines of evidence. So biological evolution is a theory: It is a well-supported, widely accepted, and powerful explanation for the diversity of life on Earth.
