Final Answer :
D
Explanation :
Experimenter bias occurs when an experimenter's preconceived notions or beliefs influence the outcome of the study. In option D, the experimenter's belief in his own hypothesis affects either the subjects' behaviour or his observations of the subjects, making it an example of experimenter bias. Option A refers to experimental design and not bias, while Option B refers to experimenter expectancy bias. Option C is an ideal scenario but not necessarily indicative of bias.
