Final answer:
The physiological component of listening is 'Receiving,' representing the body's ability to hear sounds before any further processing like interpreting or responding.
Step-by-step explanation:
The physiological component of listening is Receiving. This part of the listening process involves the initial stage where the ears pick up sound waves and the brain begins to process auditory information. Comparatively, Interpreting refers to making sense of the sounds we hear, Evaluating involves critically assessing the information, and Responding entails the actions we take after processing the information. The physiological aspect strictly relates to the body's capacity to pick up auditory stimuli before the brain engages in further analysis or response.
