For a minor burn (first-degree burn, characterized by redness and pain without blistering), what is the immediate recommended first aid step?

✓ Correct Answer: Option C

Running cool (not cold or icy) water over a minor burn helps to reduce pain, swelling, and further tissue damage. Ice can cause frostbite and further damage. Butter or oil can trap heat and increase the risk of infection. Tight bandages are not recommended for immediate cooling and could cause more pain.
