B: Heart
Answer: B: Heart 
Explanation: Bezold-Jarisch reflex
Apnea followed by rapid breathing, hypotension, and bradycardia (the coronary chemoreflex or Bezold-Jarisch reflex).
Response is produced by receptors in the heart
The receptors are probably C fiber endings, and the afferents are vagal.
Its physiologic role is uncertain, but in patients with myocardial infarcts, substances released from the infarcted tissue may stimulate ventricular receptors, contributing to the hypotension that is not infrequently a stubborn complication of this disease.
