A refutable hypothesis must allow for the possibility that the observations will not support the hypothesis. This means that it must be possible to conduct an experiment or make observations that could prove the hypothesis to be false. Refutable hypotheses also typically refer to variables that can be observed or measured, but the statement about the existence of an effect or relationship (option B) is not necessary for a hypothesis to be refutable. Option D is incorrect because a hypothesis cannot state a conclusion that has already been proven since the purpose of developing a hypothesis is to test whether it is true or not.
