B Correct answer
Explanation

Rubefacients are substances that cause redness (hyperemia) of the skin by dilating blood vessels. They work by mild irritation of the skin, increasing blood flow to the area. Counter-irritants is a broader category that includes rubefacients. Piroxicam and diclofenac are NSAIDs, not primarily used for their rubefacient effects.
