D. There is no need to rotate the choices.
Explanation / Answer
a) We construct the following table to find the mode candidate.
Since Smith has gotten the maximum number of votes in the survey, the mode candidate is SMITH.
b) Yes it is a good idea to rotate the candidate choices to avoid response bias.
While conducting any survey having multiple choices, the respondants have a tendency to quickly finsh up the survey by answering the survey questions very fast. In this process, the respondants have a tendency to pick up the first or last choice and due to this reason there arises a respondant bias towards the first and last choice. To do away with this, it is wise to rotate the candidate choices.
