Options

A. consumed products of plants growing in the lake
B. eat fish from the lake
C. eat birds dwelling in the same are
D. used same water for bathing

Answer

**Step-by-Step Solution:**

1. **Understanding DDT**: DDT (Dichloro-Diphenyl-Trichloroethane) is a pesticide that was widely used to control insect populations. It is known for its persistence in the environment and its tendency to accumulate in the tissues of living organisms.

2. **Identifying the Source of DDT Accumulation**: The question states that a lake has alarming levels of DDT. This means that organisms living in or around the lake, including plants and fish, are likely to absorb DDT from the water.

3. **Considering the Affected Population**: The question asks who would be most affected by the accumulation of DDT. This would likely include individuals who consume organisms that have absorbed DDT.

4. **Analyzing the Options**:
- **Option A**: Consuming products of plants growing in the lake. This is a valid option because plants can absorb DDT from the water and soil, leading to accumulation in their tissues.
- **Option B**: Eating fish from the lake. This is also a valid option since fish can accumulate DDT in their bodies through the water they inhabit and the food they consume.
- **Option C**: Eating birds from the lake. While birds can be affected by DDT, the question focuses on direct consumption from the lake, making this option less relevant.
- **Option D**: Using the same water for bathing. This option is less likely to cause significant accumulation of DDT in the body compared to consuming contaminated food.

5. **Determining the Most Affected Group**: Between options A and B, both are valid, but option B (eating fish from the lake) is likely to have a more significant impact due to the higher consumption rates of fish compared to plant products.

6. **Conclusion**: The people most affected by the accumulation of DDT in the body would be those who eat fish from the lake (Option B).
