Correct answer:

rejects. . . null. . . alternative


Type I errors are made when a researcher incorrectly rejects the null hypothesis and erroneously  accepts the alternative hypothesis. For example, a researcher may incorrectly conclude that two plant treatments are different by erroneously rejecting the null hypothesis. As a result they may assume that they have differing effects when they are—in fact— the same.
