C. Intestine
D. Stomach

Answer

To determine where the inner cuticle layer is present in the alimentary canal of the earthworm, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Alimentary Canal**: The alimentary canal of an earthworm consists of several parts, including the pharynx, esophagus, gizzard, and intestine. Each part has a specific function in the digestion process.

2. **Identify the Gizzard**: The gizzard is a muscular organ that is located in the 8th and 9th segments of the earthworm. It is known for its grinding action, which helps in breaking down food.

3. **Examine the Composition of the Gizzard**: The gizzard is lined with a special inner cuticle layer. This cuticle is important as it helps in the grinding process by providing a tough surface against which food can be crushed.

4. **Consider Other Parts of the Alimentary Canal**: While the pharynx and intestine are important for the initial intake and final digestion of food, they do not have the same muscular structure or inner cuticle lining as the gizzard.

5. **Conclude the Answer**: Based on the information about the structure and function of the gizzard, we can conclude that the inner cuticle layer is present in the gizzard of the earthworm.

### Final Answer:
The inner cuticle layer in the alimentary canal of the earthworm is present in the **gizzard**.
