Deoxyribonuclease and ribonuclease are secreted by

Options

A. Liver
B. Stomach
C. Pancreas
D. Kidney

Explanation

To answer the question "Deoxyribonuclease and ribonuclease are secreted by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Enzymes**:
- Deoxyribonuclease (DNase) is an enzyme that breaks down deoxyribonucleic acid (DNA).
- Ribonuclease (RNase) is an enzyme that breaks down ribonucleic acid (RNA).

2. **Identifying the Source**:
- Both DNase and RNase are nucleases, which are enzymes that hydrolyze the nucleic acids (DNA and RNA) into smaller components.

3. **Considering the Options**:
- The options provided are: liver, stomach, pancreas, or kidney.
- Among these, the pancreas is known for secreting various digestive enzymes, including nucleases.

4. **Confirming the Function**:
- The pancreas secretes DNase and RNase as part of its digestive enzyme production, which helps in the digestion of nucleic acids in the food we consume.

5. **Final Answer**:
- Therefore, the correct answer is that deoxyribonuclease and ribonuclease are secreted by the **pancreas**.
