1. (a) → (i), (b) → (iii), (c) → (ii)
2. (a) → (iii), (b) → (i), (c) → (ii)
3. (a) → (ii), (b) → (i), (c) → (iii)
4. (a) → (iii), (b) → (ii), (c) → (i)

Correct answer: (a) → (iii), (b) → (i), (c) → (ii)

Solution

Sucrose is composed of α-D-Glucose and β-D-Fructose, making it match with (ii). Lactose consists of β-D-Galactose and β-D-Glucose, corresponding to (i). Maltose is formed from two α-D-Glucose units, aligning it with (iii).
