Ответ:
The correct answer is B. False
Explanation:
A scientific theory is an accepted explanation or model about a specific phenomenon and that is created based on the Scientific Method, this implies before a scientific theory is created scientist need multiple evidence and experiments. Despite this, scientific theory as any other element in science can be disproved if scientists find new evidence that contradicts or changes the theory previously proposed. For example some centuries ago scientist and academics believed the Earth was flat, but due to new evidence and discoveries, this theory was disproven. Thus, it is false a scientific theory can never be disproven because new evidence can disprove almost any scientific theory.
