The correct option is: A QUESTIONNAIRE ON THE QUALITY OF CARE IN A HOSPITAL.
Questionnaire is one of the instruments used in scientific investigation to find out the real truth or the real state of a thing or situation. Questionnaires are usually distributed to the subjects of the experiments who supply the data that are needed for the investigation.
