Step-by-step explanation:
The benefit of a down comforter (bed spread) among the options provided is that the comforter is versatile (Option B). The versatility of a down comforter is attributed to its ability to provide comfort and warmth while being light enough for use in various seasons. Down comforters are filled with the soft plumage from the underside of geese or ducks, providing exceptional insulation. Goose feathers are often mixed with down feathers to enhance the softness, making down comforters a preferred choice for their comfort and adaptability to different sleeping preferences and climate conditions. The color, size, or thread count of the comforter, while they may be important to some consumers, do not inherently contribute to the performance or functionality of the comforter.
