B Correct answer
Explanation

If the rotting is complete, the colour of the garbage turns black and there will be no foul smell. If the garbage has not changed at all or there is foul smell, it means garbage is not rotten completely. If the rotting is not complete, cover the bags again with soil and allow bacteria to act on them.

Hence, option (2) is the correct answer.
