Correct answer: (B) Historical studies — A hypothesis may not be required in historical studies, so that is the answer.
Explanation
★A hypothesis may not be required in historical studies, so that is the answer.
★Historical studies often aim to describe and understand past events from the evidence.
★So they may proceed without a formal hypothesis, working from questions instead.
★The survey method may still test relationships and use hypotheses.
★Experimental studies always test a hypothesis, which is central to the experiment.
★Correlational studies predict how variables relate, usually as a hypothesis, so only historical studies may not require one.
