One of the Effects of Using Closed Ended Rather Than

One of the effects of using closed ended rather than open ended questions in a survey is:

A) the list of alternatives serves to remind people of responses that they might not have thought of otherwise.
B) people tend to ignore the list of alternatives and fill in their responses in the "other" category.
C) people are less likely to participate in the survey and answer all of the questions.
D) people have much more freedom to answer questions as they wish rather than as the investigator might wish them to.
