Which option correctly defines a scientific theory?

a scientist’s best guess, or assumption, about the cause of a problem

an explanation for observable facts that is supported by experimental evidence

a process of carrying out specific, well controlled tests in order to answer a scientific question

a tentative, informed answer to a scientific question

B?

I agree.

Yes, B.

thank u

Yes, option B correctly defines a scientific theory: "an explanation for observable facts that is supported by experimental evidence."

To arrive at this answer, you can analyze the options and compare them to the definition of a scientific theory. One way to do this is to break down each option and evaluate how well it aligns with the characteristics of a scientific theory.

Option A suggests that a scientific theory is "a scientist's best guess or assumption about the cause of a problem." However, a scientific theory is more than just a guess or assumption; it is an explanation supported by evidence.

Option C describes a process of carrying out specific, well-controlled tests to answer a scientific question. This option aligns more with the concept of scientific experimentation and the scientific method rather than the definition of a scientific theory.

Option D characterizes a scientific theory as a "tentative, informed answer to a scientific question." While the term "tentative" conveys the idea that theories are subject to change in light of new evidence, it does not fully capture the depth and rigor of a scientific theory.

Option B, on the other hand, accurately defines a scientific theory as an explanation for observable facts that is supported by experimental evidence. This definition reflects the key characteristics of a scientific theory, which include being based on empirical data and being well-established through rigorous testing and experimentation.
