Pyrosis is commonly known as which symptom?

• A. Heartburn
• B. Pyrosis
• C. Dental plaque
• D. Halitosis

Answer: (B)

Pyrosis is the medical term for heartburn—the burning sensation in the chest or behind the breastbone that results from stomach acid irritating the esophagus, often after meals or when lying down. This term is used in clinical contexts to describe that specific symptom, which is why it matches the common experience of heartburn. The other options refer to different things: dental plaque is a sticky film on teeth, and halitosis is bad breath. So pyrosis directly corresponds to heartburn, making it the correct pairing.
