Why are glass bottles or jars cleaned and dried before storing pickles in them?

Glass bottles and jars are used for storing pickles. Before storing pickles in them they are thoroughly cleaned and dried in the sunlight. This is done to prevent microbial growth in the jar. Even if there is a small amount of moisture left then it provides an environment for fungal growth. This process increases the longevity of the pickles.

Therefore, the correct answer is an option (C).
