Verified step by step guidance

Understand the role of the parasympathetic nervous system: It is part of the autonomic nervous system responsible for 'rest and digest' activities, which generally conserve energy and promote maintenance functions.

Identify the typical responses of the parasympathetic nervous system: These include decreased heart rate, increased digestion, and constriction of pupils.

Analyze each option provided: Consider whether each option aligns with the 'rest and digest' functions of the parasympathetic nervous system.

Evaluate 'Decreased heart rate': This is a classic parasympathetic response, as it conserves energy by slowing down the heart rate.

Compare with other options: Increased respiratory rate, increased blood pressure, and dilation of pupils are typically associated with the sympathetic nervous system, which prepares the body for 'fight or flight' responses.
