Concept:An antonym is a word with the opposite meaning. The opposite of "laconic" (using few words) is a word that means using too many words.
Explanation:"Laconic" describes a person, speech, or style that uses very few words.
For example: "His laconic reply suggested a lack of interest."
Now look at each option:
"Brief" means concise, using few words, so it is a synonym, not an antonym.
"Concise" also means giving information in few words, so it is another synonym.
"Euphoria" means intense excitement or happiness, which is unrelated to word usage.
"Verbose" means using or expressed in more words than needed.
For example: "Academic language is often obscure and verbose."
Since "verbose" is the opposite of "laconic", option D is correct.
Answer:Verbose (Option D)
