Caus- and caut- share a meaning related to which symptom?

• A. Pain
• B. Burn
• C. Fever
• D. Itch

Answer: (B)

Both caus- and caut- come from roots that mean burn. In medical terms, caustic substances burn or erode tissue, and cautery uses heat to burn tissue on purpose. Because they share the idea of burning, the related symptom is a burning sensation. Fever and itch aren’t tied to this burn meaning, and pain is a general sensation rather than the specific burning sense these roots convey. So the symptom linked to both roots is burning.
