Correct option is D
The qualities of a good paragraph include being precise and to the point. While not all good paragraphs need to be short, brevity can contribute to clarity, making (d) "More than one of the above" the correct choice. A well-constructed paragraph focuses on a single main idea, which should be clearly stated in its topic sentence. The supporting sentences should provide evidence or explanations that reinforce this main idea, and the paragraph should maintain coherence and unity throughout.
