How many of the above statements are wrong ?

Options

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

Answer

To determine how many of the statements (A-D) are wrong, let's analyze each statement one by one:

### Step 1: Analyze Statement A
- **Statement A:** The stomach stores the food for 4-5 hours.
- **Evaluation:** The stomach typically stores food for about 2 to 4 hours, not 4 to 5 hours. Therefore, this statement is **wrong**.

### Step 2: Analyze Statement B
- **Statement B:** The food mixes thoroughly with the acidic intestinal juice.
- **Evaluation:** The intestinal juice is actually alkaline in nature, not acidic. Therefore, this statement is also **wrong**.

### Step 3: Analyze Statement C
- **Statement C:** Trypsinogen is activated by an enzyme enterogastrone, secreted by the intestinal mucosa.
- **Evaluation:** Trypsinogen is activated by an enzyme called enterokinase (or enteropeptidase), not enterogastrone. Therefore, this statement is **wrong**.

### Step 4: Analyze Statement D
- **Statement D:** Renin is an enzyme found in gastric juice of infants which helps in digestion of milk protein.
- **Evaluation:** This statement is correct. Renin is indeed present in the gastric juice of infants and helps in the digestion of milk protein.

### Conclusion
- **Summary of Findings:**
- Statement A: Wrong
- Statement B: Wrong
- Statement C: Wrong
- Statement D: Correct

Thus, **3 statements are wrong** (A, B, and C).

### Final Answer
The number of wrong statements is **3**.
