On hydrolysis of starch, we finally get

Options

A. glucose
B. frutose
C. both (a) and (b)
D. sucrose

Explanation

To solve the question "On hydrolysis of starch, we finally get," we need to understand the process of starch hydrolysis and the products formed. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Starch**:
- Starch is a polysaccharide made up of multiple glucose units linked together by glycosidic bonds. It is primarily composed of two components: amylose and amylopectin.

2. **Chemical Formula of Starch**:
- The general formula for starch can be represented as (C6H10O5)n, where 'n' indicates the number of glucose units.

3. **Hydrolysis Process**:
- Hydrolysis is the chemical breakdown of a compound due to reaction with water. In the case of starch, hydrolysis can be catalyzed by enzymes (like amylase) or dilute acids.

4. **Intermediate Products**:
- During hydrolysis, starch first breaks down into smaller oligosaccharides, and then into disaccharides such as maltose (C12H22O11).

5. **Final Product**:
- Continuing the hydrolysis process, maltose can further hydrolyze into its monomeric units, which are glucose molecules (C6H12O6).

6. **Conclusion**:
- Therefore, the final product obtained from the complete hydrolysis of starch is D-glucose.

### Answer:
On hydrolysis of starch, we finally get **D-glucose**.
