The steps in the preparation of green manure are given below in a randow order. Select the option that represents these steps in the correct sequence.
(a) Green plants are decomposed in soil.
(b) Quick growing green plants are cultivated.
(c ) Plants are ploughed and mixed into the soil.
(d) After decomposition it becomes green manure.

Options

A. (c) `ne` (b) `ne` (a) `ne` (d)
B. (a) `ne` (c) `ne` (b) `ne` (d)
C. (a) `ne` (b) `ne` (c) `ne` (d)
D. (b) `ne` (c) `ne` (a) `ne` (d)

Answer

To determine the correct sequence of steps in the preparation of green manure, we can analyze the steps provided:

1. **Step (b)**: Quick growing green plants are cultivated.
- This is the first step because we need to grow the plants before any further action can be taken.

2. **Step (c)**: Plants are ploughed and mixed into the soil.
- After the plants have grown, they need to be ploughed and mixed into the soil to start the decomposition process.

3. **Step (a)**: Green plants are decomposed in soil.
- Once the plants are mixed into the soil, they begin to decompose, which is the next step in the process.

4. **Step (d)**: After decomposition, it becomes green manure.
- Finally, after the decomposition process is complete, the organic matter transforms into green manure.

Putting these steps together in the correct order, we have:
- (b) → (c) → (a) → (d)

Thus, the correct sequence is BCAD.
