Answer:
The correct answer is answer B: A closed question has fixed choices for answers, whereas an open question is a free-response question.
Step-by-step explanation:
Closed questions not always have yes-no responses, they have fixed choices for answers. For example, when someone asks for your gender, you choose between male or female, that's a type of closed question that doesn't contain a yes-no answer.
The advantages and disadvantages of each one depend a lot on the objective or the reason why you are using them.
In general terms, the advantages of the closed ones are: they are easier and quick to answer and check, the consistency of the responses is improved and they are easier to compare between respondents.
The disadvantages we have are: they could not represent the answer that the respondent wants to give, they could be answered indifferently as they don't make the respondent reflect or think an elaborated response.
For the open question, the advantages are: they permit an unlimited number of responses so they could apport richness, the respondents can express what they think about the question and they could help clarify some closed questions.
The open question's disadvantages are: they take more time and effort in being responded, all the answers given may differ between each other and we can lose control in the response's length.
