Final answer:

The correct option is d. A feeling of energy and euphoria is NOT an effect of the parasympathetic division; this is associated with the sympathetic division's 'fight-or-flight' response.

Step-by-step explanation:

The student's question relates to the effects of the parasympathetic division of the autonomic nervous system. The correct answer for the effect that is NOT associated with the parasympathetic division is d) a feeling of energy and euphoria. The parasympathetic division is primarily responsible for the 'rest-and-digest' state, which generally conserves and restores energy.

It is characterized by activities such as constriction of the pupils (a), reduction in heart rate (b), and contraction of the urinary bladder (c). In contrast, a feeling of energy and euphoria is typically associated with the sympathetic division, known for its 'fight-or-flight' response, which includes the release of neurotransmitters like epinephrine and norepinephrine that can induce such feelings.
