How long should stalks of Jute be soaked in water so that the fibers can be separated?
Correct Answer
D. About 20 days
Explanation
Jute fibers are obtained from the stalks of the jute plant.

Soaking the jute stalks in water helps to accelerate this process. After about 20 days of soaking, the lignin breaks down sufficiently, allowing the fibers to be separated easily.
