Answer: B
Cold is the right choice in the first 24 to 48 hours after an acute injury. It constricts blood vessels, limits swelling and bleeding into the tissue, and numbs the area. The pack is wrapped and limited to about 20 minutes to protect the skin.
Why the others are wrong
Heat dilates vessels and increases swelling in a fresh injury, so it is saved for later when stiffness is the main problem. A heating pad left on overnight risks a burn on top of making the swelling worse. Moving a newly sprained joint every hour works against rest and can extend the injury.
