A hypothesis is:
A tentative statement providing an explanation.
A hypothesis is a tentative, testable proposition that a researcher formulates as a possible answer to the research problem before data are collected. It states an expected relationship between variables and offers a provisional explanation that the study will later confirm or reject through evidence.
The description a tentative statement providing an explanation captures this exactly, because a hypothesis is provisional (not proven) and its role is to explain or predict.
The option calling it a certain and established finding is wrong, since a hypothesis is unproven and awaits testing; a certain finding is a conclusion, not a hypothesis. A part of the research question is incorrect because the research question and the hypothesis are distinct stages; the hypothesis is derived from the question but is not merely a part of it. A strategy of evaluating data confuses the hypothesis with data-analysis methodology. Hence the tentative explanatory statement is correct.
Correct answer: A tentative statement providing an explanation.
