After taking her English final, Nayeesha attempts to relax in her chair by meditating. She is attempting to reduce her heart and respiration rates, as well as her muscular tension. In this scenario, her physiological relaxation can be best attributed to the functioning of her nervous system.

In this scenario, her physiological relaxation can be best attributed to the functioning of her parasympathetic nervous system.

Explanation:

A division of the autonomic nervous system (ANS), the parasympathetic nervous system is responsible for the body's rest and digestion response. It is the system that acts when we are relaxed, or when we are feeding or resting. This systems increases digestion and decreases our breathing and heart rates. In other words, it undoes the work of the sympathetic systems.
