Answer to Question 1

D
Demand characteristics are features of the research that make people behave differently than they normally would. Unobtrusive research is conducted without the participants realizing they are participating in research. This makes it possible only to record their public behavior, and such behavior is unaffected by demand characteristics.

When the researcher is unobtrusive, his presence as a researcher is not detected by the participants.
