Which drug is used as a muscle relaxant?

Explanation:
Muscle relaxants relieve muscle spasms by dampening nerve signals to the muscles. Cyclobenzaprine is a centrally acting skeletal muscle relaxant commonly used for short-term relief of acute muscle spasm due to strains or sprains, making it the best fit for this role. The other options do not act as muscle relaxants: acetaminophen relieves pain without anti-inflammatory effect, ibuprofen reduces pain and inflammation as an NSAID, and diphenhydramine is an antihistamine with sedative effects—not a muscle relaxant.
