How many of the above statements are correct?

Options

A. Four
B. One
C. Two
D. Three

Answer

To determine how many of the provided statements are correct, we will analyze each statement one by one:

### Step-by-Step Solution:

1. **Statement (a): "Digestion of protein is completed in stomach."**
- This statement is **incorrect**. The digestion of proteins begins in the stomach with the action of gastric juices but is completed in the small intestine with the help of enzymes like trypsin and chymotrypsin.

2. **Statement (b): "Enterokinase is a nondigestive enzyme."**
- This statement is **correct**. Enterokinase is an enzyme that activates trypsinogen to trypsin, which is essential for protein digestion, but it does not directly digest food itself.

3. **Statement (c): "Haustra are enlarged rectal veins."**
- This statement is **incorrect**. Haustra are pouches or sac-like structures in the colon, while enlarged rectal veins are referred to as hemorrhoids or piles.

4. **Statement (d): "For activity of carboxypeptidase, Zn is required."**
- This statement is **correct**. Carboxypeptidase is a digestive enzyme that requires zinc as a cofactor for its activity.

5. **Statement (e): "Spicy food may cause indigestion."**
- This statement is **correct**. Spicy foods can irritate the digestive tract and lead to symptoms of indigestion in some individuals.

Now, let's summarize the correctness of each statement:
- Statement (a): Incorrect
- Statement (b): Correct
- Statement (c): Incorrect
- Statement (d): Correct
- Statement (e): Correct

### Conclusion:
Out of the five statements, **three statements are correct** (b, d, and e).

### Final Answer:
**3 statements are correct.**
