Which statement about the D to Z color scale is true?

Explanation:
Diamond color is graded on a fixed alphabetical scale that runs from D to Z. D represents colorlessness, meaning no detectable color, while Z represents a noticeable light yellow or brown tint. As you move down the scale from D to Z, the color becomes increasingly apparent. This standardized range lets gemologists compare diamonds reliably. The other options don’t fit because they propose starting or ending letters outside the accepted D-to-Z range or use a different subset that isn’t used in diamond color grading.
