Identify the most appropriate ANTONYM of the highlighted word in the following sentence.
"Dipesh loves to answer his boss’s questions in tactful ways."

Explanation of the Correct Answer:

· The correct antonym is "Undiplomatic," which means lacking tact, being blunt or insensitive.
Example Sentences:
· She gave a tactful reply to avoid offending her colleague.
· His undiplomatic remarks created tension during the meeting.
Other options:
· (a) "Affordable" → Incorrect because it relates to cost, not behavior.
