The correct answer is B) yellow top and gray body. The color-coding of refrigerant recovery cylinders, regardless of the refrigerant contained within, is standardized to ensure proper identification and safe handling. As per industry regulations, the correct color-coding is a yellow top and gray body. The other answer choices are incorrect because they do not align with the established color standards. Light blue and yellow (A) or gray and light blue (C) are not the recognized colors, while gray and yellow (D) is the reverse of the proper coding.
