The correct answer is D. Nalanda.
Handloom is a traditional method of weaving cloth using a hand-operated loom. It is a labor-intensive process that requires skilled artisans to produce high-quality fabrics. Handloom weaving is practiced in many parts of India, but it is particularly well-developed in the states of Bihar, Uttar Pradesh, and West Bengal.
The districts of Kishanganj, Bhagalpur, and Siwan are all located in the state of Bihar, which is one of the leading producers of handloom cloth in India. These districts are home to a large number of handloom weavers who produce a variety of fabrics, including cotton, silk, and wool.
The district of Nalanda, on the other hand, is not as well-known for its handloom weaving. There are a few handloom weavers in the district, but they produce a relatively small amount of cloth. The main reason for this is that the climate in Nalanda is not ideal for handloom weaving. The high humidity and temperature can damage the fibers of the cloth, making it difficult to produce high-quality fabrics.
In conclusion, the correct answer to the question “In which of the following places handloom is not developed?” is D. Nalanda.
