Select the option that can be used as a one-word substitute for the given…

Concept

A one-word substitution replaces a group of words with one word that preserves the same precise meaning.

For sensory descriptions, identify both the sense involved—smell or taste—and the exact quality, such as sharpness, sweetness, or freshness.

Application

The phrase specifies an intensely strong and sharp smell or taste. “Pungent” carries exactly this sensory meaning, so the required word is “Pungent.”

Contrast

• “Zesty” refers to a lively, tangy, often citrus-like flavour.

• “Robust” means strong, vigorous, or full-bodied more generally.

• “Pungent” specifically denotes a powerfully sharp, penetrating smell or taste.

• “Savory” describes a salty or spicy taste rather than a sweet one.

Result

Therefore, the one-word substitute is “Pungent.”
