Correct Answer:
A. Praise
The correct answer is Praise. The word 'reproach' means to express disapproval, criticism, or blame towards someone. Its antonym (opposite) is 'praise', which means to express approval, admiration, or commendation. 'Blame' is a synonym of reproach, 'Support' is not a direct antonym, and 'Dishonor' is unrelated. Therefore, Praise is the correct antonym.
