The correct answer is:
Cities | Industries

Bhagalpur | Silk
Kishanganj | Tea
Purnia | Jute
Gopalganj | Sugar
Bhagalpur is known for its silk industry. The city is home to many silk mills and factories, and its silk is known for its high quality.
Kishanganj is known for its tea industry. The city is home to many tea gardens, and its tea is known for its strong flavor.
Purnia is known for its jute industry. The city is home to many jute mills and factories, and its jute is known for its high quality.
Gopalganj is known for its sugar industry. The city is home to many sugar mills and factories, and its sugar is known for its high quality.
The other options are incorrect because they do not match the cities with the correct industries. For example, option A matches Bhagalpur with tea, but Bhagalpur is actually known for its silk industry.
