The correct answer is: B. Bhagalpur
Tasar silk is a type of silk produced from the cocoons of the tasar silk moth, Antheraea assamensis. It is a wild silk, meaning that it is produced by moths that live in the wild, rather than being reared in captivity. Tasar silk is known for its beautiful luster and its strength. It is also a very sustainable silk, as the tasar silk moth does not require any pesticides or fertilizers to produce its cocoons.
The tasar silk industry is located in the Bhagalpur district of Bihar. The district is home to a number of villages where the tasar silk moth is reared. The silk is then spun and woven into fabric by hand. The tasar silk industry is an important source of income for many people in the Bhagalpur district.
The other options are incorrect because:
- Katihar is a district in Bihar, but it is not known for its tasar silk industry.
- Buxar is a district in Bihar, but it is not known for its tasar silk industry.
- Begusarai is a district in Bihar, but it is not known for its tasar silk industry.
