Step 1: Start by picking the clearest antonym in the option list. 'Wordy' means using far more words than necessary, which is the direct opposite of 'terse'.
Step 2: Since a synonym must move in the opposite direction from this antonym, eliminate 'wordy' and check the remaining three for a match to brevity. 'Polite' describes courteous manner, not length or word count, so it is unrelated. 'Confusing' describes clarity, not length, and terse writing is usually clear, not confusing, so this does not fit either.
Step 3: 'Brief and concise' describes exactly the opposite of 'wordy', meaning short and to the point, which is the true meaning of 'terse'.
Correct option: (3) Brief and concise.
