A
Increased heart rate
B
Decreased heart rate
C
energy diversion to muscles
D
dilated pupils
Explanation: 

Detailed explanation-1: -In contrast, parasympathetic stimulation decreases heart rate and constricts the pupils. It also increases secretion of the eye glands, increases peristalsis, increases secretion of salivary and pancreatic glands, and constricts bronchioles.

Detailed explanation-2: -The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.[1]

Detailed explanation-3: -The range of responses that the parasympathetic nervous system control include actions such as decreased heart rate, decreased blood sugar as liver cells take in glucose for storage, increased digestive activity, and constriction of the pupils.
