Question

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

Explanation:

A scientific theory requires rigorous testing and consistent support from a large body of empirical data to be accepted by the scientific community. Controversy alone does not validate a theory, single experiments are insufficient to establish a theory, and theories can revise or replace previous ideas when new evidence emerges.

Answer:

widely tested and supported by extensive data
