AHistorical research
BPhilosophical research
CField experimentation ✓ Correct
DAll of the above
Correct answer: (C) Field experimentation — Field experimentation is termed controlled observation, so that is the answer.
Explanation
★Field experimentation is termed controlled observation, so that is the answer.
★In a field experiment the researcher observes behaviour while controlling key conditions.
★So it combines real-setting observation with the control that marks an experiment.
★Historical research observes past records but cannot control the conditions of past events.
★Philosophical research reasons about ideas and does not involve controlled observation at all.
★So among these, only field experimentation is controlled observation.
