The question is about understanding how to emphasize the greatness of something described as 'splendid'. The correct answer is B. absolutely, as 'absolutely splendid' emphasizes the extent of the greatness. Option A. really is also used for emphasis, but it is less strong than 'absolutely'. Option C. merely means 'only' or 'simply', which is the opposite of emphasis. Option D. dramatically is used to indicate a strong effect or change, not specifically for emphasis on 'splendid'.
