Cuticle of annelids is

Options

A. Non-chitinous and albuminoid
B. Chitinous
C. Chitinous and albuminoid
D. Non-chitinous

Answer

### Step-by-Step Solution:

1. **Understanding Annelids**: Annelids belong to the phylum Annelida, which includes organisms such as earthworms and leeches. They are characterized by their segmented bodies.

2. **Identifying the Cuticle**: The cuticle in annelids is a protective layer that covers their body. It is important to note that this cuticle serves various functions, including protection and aiding in respiration.

3. **Type of Cuticle**: The cuticle of annelids is described as non-chitinous. This means it does not contain chitin, which is a common component in the exoskeletons of arthropods (like insects and crustaceans).

4. **Composition of the Cuticle**: The cuticle of annelids is albuminoid, which refers to a class of simple proteins. Albuminoid proteins include substances like collagen and elastin, which provide structural support.

5. **Conclusion**: Therefore, the cuticle of annelids is non-chitinous and albuminoid, distinguishing it from the chitinous cuticle found in arthropods.

### Final Answer:
The cuticle of annelids is non-chitinous and albuminoid.
