The correct order for converting kitchen garbage into manure is as follows :
ii. Cover the bottom of a pit with sand.
i. Put garbage into the pit.
iv. Add worms.
iii. Cover the pit loosely with the gunny bag or grass.

1. This is the proper manner of garbage disposal.
2. It allows the proper degradation of biodegradable wastes.
3. The worms decompose the waste.
4. The grass or gunny bags act like a lid to prevent the foul smell to escape.
5. Once the decomposition is complete, the waste is converted to manure that mixes with the sand or soil pit.
6. It is extremely fertile and rich in nutrients.
7. This process is called vermicomposting as it makes use of worms for composting garbage.

Explanation of the incorrect options:

Option A:

2. And in the second step put the garbage into the pit.
3. The worms decompose the waste without that we cannot cover the pit loosely with a gunny bag or grass.
4. Hence, this option is incorrect.

Option B:

1. In the first step, cover the bottom of the pot with a layer of sand.
2. Hence, this option is also incorrect.

Option C:

1. In the first step, cover the bottom of the pot with a layer of sand.
2. And in the second step put the garbage into the pit before that worms cannot be added.
