People taking lot of salt experience puffiness or swelling of the body due to

Options

A. water retention in tissue cells and intercellular spaces because of osmosis
B. water loss from the cells through skin tissues
C. capillary action of water through skin pores
D. excessive thirst and drinking more water .

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks why people who consume a lot of salt experience puffiness or swelling in their bodies.

2. **Analyzing the Options:**
We have four options to consider:
- A) Water retention in tissue cells and intercellular spaces because of osmosis.
- B) Water loss from the cells through the skin tissues.
- C) Capillary action of water through the skin pores.
- D) Excess thirst and drinking more water.

3. **Identifying the Relevant Concept:**
The key concept here is osmosis, which is the movement of solvent (water) from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

4. **Applying Osmosis to the Situation:**
When a person consumes a lot of salt, the concentration of salt (solute) in the body increases. This leads to a higher concentration of solute inside the cells compared to the surrounding fluid. As a result, water moves into the cells from the surrounding areas to balance the concentration of solute, causing the cells to swell or become puffy.

5. **Evaluating the Options:**
- Option A correctly describes this process: water is retained in the tissue cells and intercellular spaces due to osmosis.
- Option B is incorrect because it suggests water loss, which does not explain puffiness.
- Option C is irrelevant to the swelling caused by salt intake.
- Option D mentions thirst and drinking more water, but it does not directly explain the puffiness caused by salt.

6. **Conclusion:**
The correct answer is **Option A: Water retention in tissue cells and intercellular spaces because of osmosis.**
