Solution

The correct option is A Paracetamol
Various phenolic coal tar derivatives have analgesic (pain-killer) properties. These include acetanilide, phenacetin, and paracetamol (acetaminophen). Paracetamol is the only coal-tar derived analgesic still in use today, but industrial phenol is now usually synthesized from crude oil rather than coal tar.
