Endorphins are natural pain relievers produced by the brain. Hormones (A) and endocrines (B) are broad categories of signaling molecules produced by the body, but do not specifically refer to pain relief. Neuropeptides (D) are a type of molecule involved in neurotransmission, but not all neuropeptides are pain relievers.
