Lactose is hydrolysed into
(a) Glucose + Fructose
(b) Fructose only
(c) Glucose +Galactose
(d) Glucose only

Options

A. Glucose + Fructose
B. Fructose only
C. Glucose +Galactose
D. Glucose only

Answer

To solve the question "Lactose is hydrolysed into," we need to understand the composition of lactose and the process of hydrolysis.

### Step-by-Step Solution:

1. **Identify the Composition of Lactose**:
- Lactose is a disaccharide, which means it is made up of two monosaccharide units.

2. **Know the Monosaccharides in Lactose**:
- The two monosaccharides that make up lactose are glucose and galactose.

3. **Understand the Hydrolysis Process**:
- Hydrolysis is a chemical reaction in which water is used to break down a compound. In the case of lactose, it is hydrolyzed by the enzyme lactase.

4. **Determine the Products of Hydrolysis**:
- When lactose is hydrolyzed, it breaks down into its constituent monosaccharides: glucose and galactose.

5. **Evaluate the Options Given**:
- (a) Glucose + Fructose - Incorrect (this is the product of sucrose hydrolysis)
- (b) Fructose only - Incorrect
- (c) Glucose + Galactose - Correct
- (d) Glucose only - Incorrect

6. **Conclusion**:
- The correct answer is (c) Glucose + Galactose.

### Final Answer:
(c) Glucose + Galactose
