In rabbit proteins are digested by

Options

A. Pepsin and trypsin
B. Trypsin and steapsin
C. Steapsin and pepsin
D. All the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Protein Digestion**: In rabbits, proteins are broken down into smaller peptides and amino acids through the action of specific enzymes.

2. **Role of Pepsin**: The first enzyme involved in protein digestion is pepsin, which is secreted in the stomach. Pepsin is responsible for breaking down proteins into smaller peptides.

3. **Role of Trypsin**: After the stomach, the partially digested proteins move into the small intestine, where another enzyme called trypsin continues the digestion process. Trypsin further breaks down the peptides into even smaller peptides and amino acids.

4. **Conclusion**: Both pepsin and trypsin play crucial roles in the digestion of proteins in rabbits. Therefore, the correct answer to the question is that proteins in rabbits are digested by both pepsin and trypsin.

5. **Final Answer**: The correct option is "all of the above" since both pepsin and trypsin are involved in protein digestion.
