Force of cohesion develops due to

Options

A. Attraction between similar molecules
B. Attraction between different molecules
C. Surface tension at the interface
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Cohesion**:
- Cohesion refers to the force of attraction between molecules of the same substance. In the context of water, it is the attraction between water molecules.

2. **Identifying the Nature of the Force**:
- The force of cohesion is specifically due to the intermolecular forces that exist between similar molecules. For water, this is primarily due to hydrogen bonds.

3. **Role of Hydrogen Bonds**:
- Water molecules have a polar nature, where the oxygen atom is more electronegative than the hydrogen atoms. This polarity allows for hydrogen bonds to form between water molecules, leading to strong cohesive forces.

4. **Effects of Cohesion**:
- The cohesive forces between water molecules contribute to phenomena such as surface tension, which allows water to resist external forces and maintain its shape.

5. **Conclusion**:
- Based on the explanation, the correct answer to the question "Force of cohesion develops due to" is **attraction between similar molecules**.

### Final Answer:
The force of cohesion develops due to **attraction between similar molecules**.
