Read the statements A, B, C and D given below. Select the option which correctly states whether the statement is True (T) or False (F).. A. Gastric glands of the stomach mucosa have oxyntic / chief cells which secrete HCI. B. Rennin is a proteolytic enzyme found in gastric juice in infants which helps in the digestion of milk proteins. C. Fructose and some amino acids like glycine are absorbed with the help of carrier ions Na+ called facilitated transport D. Vomiting is a reflex action controlled by the vomit centre in hypothalamus.

Options

A. `{:(A,B,C,D),(T,T,T,F):}`
B. `{:(A,B,C,D),(F,T,T,F):}`
C. `{:(A,B,C,D),(F,F,T,T):}`
D. `{:(A,B,C,D),(F,T,F,T):}`

Answer

To determine the truth value of each statement A, B, C, and D, we will analyze them one by one.

### Step-by-Step Solution:

1. **Statement A**: "Gastric glands of the stomach mucosa have oxyntic / chief cells which secrete HCl."
- **Analysis**: The gastric glands contain two main types of cells: parietal (or oxyntic) cells that secrete hydrochloric acid (HCl) and chief cells that secrete pepsinogen (the inactive form of the enzyme pepsin). Therefore, the statement incorrectly attributes the secretion of HCl to chief cells.
- **Truth Value**: **False (F)**

2. **Statement B**: "Rennin is a proteolytic enzyme found in gastric juice in infants which helps in the digestion of milk proteins."
- **Analysis**: Rennin (or chymosin) is indeed a proteolytic enzyme present in the gastric juice of infants, specifically for digesting casein, a milk protein. This statement is accurate.
- **Truth Value**: **True (T)**

3. **Statement C**: "Fructose and some amino acids like glycine are absorbed with the help of carrier ions Na+ called facilitated transport."
- **Analysis**: Fructose is absorbed via facilitated diffusion, and some amino acids are absorbed through sodium-dependent transport mechanisms. This statement is correct as it describes the process of absorption accurately.
- **Truth Value**: **True (T)**

4. **Statement D**: "Vomiting is a reflex action controlled by the vomit centre in hypothalamus."
- **Analysis**: The vomiting center is located in the medulla oblongata, not the hypothalamus. Thus, this statement is incorrect.
- **Truth Value**: **False (F)**

### Summary of Truth Values:
- A: False (F)
- B: True (T)
- C: True (T)
- D: False (F)

### Final Answer:
The correct truth values for the statements are:
- A: F
- B: T
- C: T
- D: F
