While storing cotton and woollen clothes, the growth of fungus and mold can be prevented by using :

Question

Accepted Answer

Option 4 is the correct answer because it encompasses all the methods mentioned in the other options, each of which contributes to preventing the growth of fungus and mold on cotton and woollen clothes. Here's a detailed explanation:

1. **Neem leaves and moth balls**: Neem leaves have natural antifungal and antibacterial properties, which help in keeping insects and mold at bay. Moth balls, typically made of naphthalene or paradichlorobenzene, are effective in repelling moths and other insects that can damage clothes. Together, they provide a strong defense against mold and fungus by keeping the environment dry and insect-free.

2. **Muslin Cloth**: Muslin cloth is a breathable fabric that allows air circulation around stored clothes. This circulation helps in reducing moisture build-up, which is a primary cause of mold and fungus growth. By wrapping clothes in muslin, you create a barrier that protects them from dust and pests while allowing them to breathe.

3. **Newspaper**: Newspapers can absorb moisture due to their paper material, which helps in keeping the storage area dry. Additionally, the ink used in newspapers has some insect-repelling properties. By lining storage areas with newspaper, you can reduce humidity and deter pests, thus preventing mold and fungus growth.

By using all these methods together, you create a comprehensive approach to protecting cotton and woollen clothes from mold and fungus. Each method contributes uniquely to the prevention process, making Option 4 the most effective choice.
