The correct answer is option D. Experiments, Observation, and Measurement.

Psychology as a science encompasses a range of methods and approaches to study the human mind and behavior. It involves conducting experiments, making observations, and utilizing measurements to gather data and draw conclusions.

Experiments allow researchers to manipulate variables and observe the effects on behavior, cognition, or other psychological phenomena. By controlling and manipulating variables, researchers can establish cause-and-effect relationships and test hypotheses.

Observation involves systematically watching and recording behavior or mental processes in natural or controlled settings. It helps psychologists gather information about human behavior in real-world contexts.

Measurement is an essential aspect of psychology, as it involves quantifying and assessing various psychological variables. Psychologists use standardized tests, surveys, questionnaires, and other measurement tools to collect data and obtain numerical or categorical information about individuals' thoughts, emotions, behaviors, or traits.

By combining experiments, observation, and measurement, psychologists can generate empirical evidence and develop theories that contribute to our understanding of human psychology.

Therefore, the correct answer is option D. Experiments, Observation, and Measurement, as these methods are fundamental to the scientific study of psychology.
