Which term describes something that is biting or sarcastic, as in a caustic wit?

• A. Rectitude
• B. Opus
• C. Caustic
• D. Desultory

Answer: (C)

The idea being tested is describing language that is sharp and biting. Caustic describes humor or remarks that are harshly sarcastic and wounding, with a sense of burning wit. It captures the feel of a caustic wit: clever, piercing, and often stingingly funny. The metaphor here comes from acids that burn; applied to speech, it means comments that burn away pretension with cutting insight. For example, a caustic remark might slice through a weak argument with dry, precise sarcasm. The other terms don’t fit: rectitude means moral uprightness; opus refers to a musical or literary work; desultory means lacking plan or focus. So caustic is the best fit.
