Concept:The antonym of a word is its opposite in meaning. Audacity means boldness or daring, often with arrogance, so its opposite is humility or lack of arrogance.
Explanation:Audacity refers to boldness or daring, especially when it involves disrespect or arrogance. For example, "He had the audacity to interrupt the speaker."
Modesty means humility and a lack of pretentiousness. It is the direct opposite of audacity because audacity shows overconfidence, while modesty shows restraint.
The other options are synonyms or related to boldness: Boldness, Bravery, and Cowardice (which is fear, not the opposite of audacity).
Thus, the correct antonym is Modesty.
Answer:Modesty (Option D)
