Answer 1

The correct option is (c) Render insensitive to pain by binding to opioid receptors

The best explanation: Analgesics, or pain killers, that bind to opioid receptors which are found principally in the CNS and Gastrointestinal tract. Most of the time increase the pain threshold level thus decreasing the patient’s perception of the occurring pain.
