The data collection is

A) best turned over to the program staff since they are on the scene and can easily handle the activity.
B) to be handled by someone without direct knowledge of the setting of the program since it is usually a rather mechanical process.
C) likely to be corrupted even by well-meaning program staff members if they are permitted to control data collection.
D) fairly simple since confidentiality is not an issue in applied social research projects.
