Solution

The correct option is B
Container was not airtight

Mold spores can accumulate in the dust around the atmosphere, which is kicked up through cleaning or even someone walking by. The spores can then settle on bread and the bread molding process will begin. Mould will not only live and feed on bread, it will also reproduce there. This is why bread kept in a container got spoiled if you let it sit there long enough.
