Read the following and find out the correct statement?
(I) In paramecium, cilia helps in locomotion and food collection
(II)In Euglena, flagella helps in locomotion and food collection
(III)In hydra tentacles help in locomotion only
(Iv)Limb movements only locomotion

Options

A. All except I
B. All except IV
C. Only I
D. Only II

Answer

To solve the question, we need to evaluate each statement provided and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Statement I**:
- **Statement**: In paramecium, cilia helps in locomotion and food collection.
- **Analysis**: This statement is correct. Cilia in paramecium are responsible for both moving the organism through water and aiding in the collection of food.

2. **Evaluate Statement II**:
- **Statement**: In Euglena, flagella helps in locomotion and food collection.
- **Analysis**: This statement is incorrect. The flagella in Euglena primarily assist in locomotion, while food collection is not a function of the flagella.

3. **Evaluate Statement III**:
- **Statement**: In hydra, tentacles help in locomotion only.
- **Analysis**: This statement is also incorrect. The tentacles of hydra are used for both locomotion and capturing food.

4. **Evaluate Statement IV**:
- **Statement**: Limb movements only locomotion.
- **Analysis**: This statement is incorrect as well. Limb movements can serve multiple functions, including locomotion, but they can also be involved in other activities such as grasping or manipulation.

5. **Conclusion**:
- The only correct statement is **Statement I**. Therefore, the correct answer is that only Statement I is true.

### Final Answer:
The correct statement is **(I) In paramecium, cilia helps in locomotion and food collection.**
