A student investigated two milk samples, X and Y, using Benedict’s test. Each milk sample was heated in a water-bath to $100\,^{\circ}\text{C}$ with Benedict’s solution, and the time until the first colour change appeared was recorded. The findings are given in the table. X: 13 s Y: 26 s Which row identifies the biological molecule detected in each milk sample and the milk sample with the greater concentration of this biological molecule?
- Aglucose; X
- Bglucose; Y
- Creducing sugar; X
- Dreducing sugar; Y
