The correct answer is B. A scientific law describes what occurs every time in a situation.
Step-by-step explanation:
In science and all differents that belong to it such as chemistry, physics or astronomy, a scientific law refers to a statement that describes an event or phenomenon and that is consistent all times. Indeed, scientific laws are created based on multiple similar experiments or observations that show the results are consistent or the same phenomenon occurs in the same way under the same conditions. Therefore, the statement that describes a scientific law is that it "describes what occurs every time in a situation" as it focuses on a phenomenon that occurs, in the same way, every time.
