Quizplus · Accepted Answer

Item difficulty analysis is used to determine the proportion of people who chose the correct response to an item. A is incorrect because it refers to the concept of item discrimination rather than item difficulty. B and D are also incorrect as they do not provide information on the proportion of people who chose the correct response.
