Which of the following statements are correct regarding liquid state?
(i) Particle are loosely packed in the liquid state.
(ii) Fluidity is maximum in the liquid state.
(iii) Liquids cannot be compressed much.
(iv) Liquids take up the shape of any container in which they are placed.

Options

A. I, II and III
B. I, III and IV
C. I, II and IV
D. All statement are correct

Explanation

To determine which statements are correct regarding the liquid state, let's analyze each statement one by one:

1. **Statement (i): Particles are loosely packed in the liquid state.**
- In the liquid state, particles are indeed loosely packed compared to solids. They have more space between them than in solids, allowing them to move around each other. This statement is **correct**.

2. **Statement (ii): Fluidity is maximum in the liquid state.**
- Fluidity refers to the ability of a substance to flow. While liquids do have fluidity, gases have even greater fluidity. Therefore, this statement is **incorrect**.

3. **Statement (iii): Liquids cannot be compressed much.**
- Liquids are generally incompressible, meaning they do not change volume significantly under pressure. This is due to the close packing of particles, which limits their ability to be compressed. This statement is **correct**.

4. **Statement (iv): Liquids take up the shape of any container in which they are placed.**
- Liquids do not have a fixed shape and will conform to the shape of their container. This characteristic is a defining property of liquids. This statement is **correct**.

Based on the analysis:
- **Correct Statements**: (i), (iii), and (iv)
- **Incorrect Statement**: (ii)

### Final Conclusion:
The correct statements regarding the liquid state are:
1. Particles are loosely packed in the liquid state.
3. Liquids cannot be compressed much.
4. Liquids take up the shape of any container in which they are placed.
