D. Glucose is reducing sugar while sucrose is non-reducing sugar

Answer

To solve the question regarding why the osmotic pressure of 0.1 M glucose and 0.1 M sucrose solutions are the same, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Osmosis**:
- Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration until equilibrium is reached.

**Hint**: Remember that osmosis involves the movement of water, not solute particles.

2. **Defining Osmotic Pressure**:
- Osmotic pressure is the pressure required to prevent the inward flow of water across a semipermeable membrane. It is a measure of the tendency of water to move into a solution.

**Hint**: Osmotic pressure is related to how much solute is present in the solution.

3. **Factors Affecting Osmotic Pressure**:
- The osmotic pressure of a solution depends primarily on the concentration of solute particles in the solution. It does not depend on the type of solute but rather on the number of solute particles.

**Hint**: Focus on the concentration of solute particles rather than their chemical nature.

4. **Comparing Glucose and Sucrose**:
- In this question, both glucose and sucrose are present at the same molarity (0.1 M). This means they have the same concentration of solute particles in the solution.

**Hint**: Concentration is key; both solutions have the same molarity.

5. **Conclusion**:
- Since both solutions (0.1 M glucose and 0.1 M sucrose) have the same concentration of solute particles, they exert the same osmotic pressure. Therefore, the correct reason for their equal osmotic pressure is that they are both present in the same concentration.

**Hint**: The equality of osmotic pressure arises solely from the equal concentration of solute.

### Final Answer:
The osmotic pressure of 0.1 M glucose and 0.1 M sucrose solutions are the same because both are present in the same concentration.
