Final answer:
A scientific theory is a well-supported explanation for events that is widely accepted as true. It is not an unproven hypothesis, as a hypothesis is a possible answer that needs to be tested further. Theories are an integral part of the scientific method. So, the correct answer is option d.
Step-by-step explanation:
A scientific theory is a well-supported explanation for events that is widely accepted as true. It is not an unproven hypothesis, as a hypothesis is a possible answer that needs to be tested further. All scientists are not required to accept a theory, as scientific theories are continually tested and modified as new evidence emerges. Theories are an integral part of the scientific method, as they contribute to our understanding of natural phenomena and guide further research.
So, the correct answer is option d.
