Choose one of the following alternative statements given below which correctly explains the process of osmosis.

Options

A. Movement of water from regions of concentrated to dilute solutions.
B. The passage of solute from weak solution to strong solution through a selectively permeable membrane.
C. A passive transport of a solvent through a selectively permeable membrane from a region of low solute concentration to a region of high solute concentration.
D. An energy dependent transport of a solvent through a selectively permeable membrane from a region of low solute concentration to a region of high solute concentration.

Explanation

To solve the question regarding the correct explanation of the process of osmosis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Osmosis**:
- Osmosis is the movement of water (solvent) across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration.

2. **Identify the Key Characteristics of Osmosis**:
- It involves the movement of water, not solute.
- Water moves towards the area with a higher concentration of solute (more solute).
- This process occurs through a semi-permeable membrane.

3. **Evaluate the Given Statements**:
- **Statement 1**: "The movement of water from regions of concentrated to dilute."
- This is incorrect because water moves from dilute (low solute) to concentrated (high solute).
- **Statement 2**: "The passage of solute from weak solution to strong solution."
- This is incorrect because osmosis refers to the movement of water, not solute.
- **Statement 3**: "The passive transport of solvent."
- This is correct as it describes the movement of water (solvent) without the need for energy, from low solute concentration to high solute concentration.
- **Statement 4**: "This is not an energy dependent process."
- While this is true, it does not correctly describe the process of osmosis itself.

4. **Select the Correct Statement**:
- The correct statement that accurately explains the process of osmosis is **Statement 3**: "The passive transport of solvent."

### Final Answer:
The correct explanation of the process of osmosis is: **The passive transport of solvent.**
