Final answer:
An hypothesis is a proposed, testable and falsifiable answer to a question based on observation, serving as a tentative explanation.
Step-by-step explanation:
The best definition for the term hypothesis is B. A hypothesis is the proposed answer to a question that was derived from an observation. In scientific methodology, a hypothesis is considered an educated guess that is testable and falsifiable. It is a tentative or proposed explanation, which means scientists must be able to conduct experiments to test whether the hypothesis can correctly predict outcomes. An example of this could be, "If my hypothesis is correct, I should see a certain result when I perform a specific test." A characteristic of a hypothesis is its flexibility; it can be revised or discarded in light of new evidence.
