Interdisciplinary Understanding

Correct answer: A. Understanding fitness from physiology, motivation from psychology and teamwork from sociology

The governing concept is interdisciplinary understanding: physical education uses relevant knowledge from several disciplines to explain and improve movement and participation. Physiology helps explain fitness, body responses, and training; psychology helps explain motivation, confidence, attention, and behaviour; sociology helps explain teamwork, group roles, culture, and cooperation. Option A is correct because it connects each discipline with a meaningful physical-education question and then applies the combined understanding in practice. B is simple recall, C is one isolated measurement, and D is merely an action or piece of equipment. None of those alternatives demonstrates integration of knowledge across subjects.
