You Will Conduct a Survey in Three Months in the School

You will conduct a survey in three months in the school registration centre to find out how the procedure for adding/dropping courses could be improved.You have several closed questions prepared for the survey,but you don't know if the choices provided are adequate.You should:

A) conduct a pre-test with open questions to find commonly chosen categories.
B) convert the closed questions into open questions,even though it will take respondents twice as long to fill the survey out.
C) conduct a pre-test to make sure that the terms used mean different things to different people.
D) conduct the survey as it is,and leave an "other" line for each question.
