Solution
The correct option is B Growth and branching of fruits in a and b horizon
The correct option is situation B.
Explanation for correct option:
- Situation B is advantageous for the absorption of water and minerals.
- It is because the A and B horizons are rich in humus, water, and minerals, due to which the soil is very fertile. So in this region, growth and branching of roots take place effectively.
- A plant can easily uptake nutrients from the soil on this horizon.
Explanation for incorrect option:
- Situation A is incorrect because in C-horizon the soil is not much fertile as in the A and B horizons.
- Water, humus, and minerals are not present here. So it is difficult for plants to grow in this region.
Final answer: Situation B is advantageous for the absorption of water and minerals.
