Which solution contained a single dye?

• A. S1
• B. S2
• C. S4
• D. S3

Answer: (D)

A single dye in a solution appears as one uniform color; if there are two or more dyes present, or if the dye separates into components, you’ll see multiple colors or distinct color bands. In the results, the sample that shows only one color across the entire solution indicates it contains just one dye, while the other samples display more than one color or multiple bands, signaling mixtures of dyes or dye components. That clean, single-color result is what identifies the solution with a single dye.
