The correct answer is: A) Mahabubnagar district.

Sericulture is the practice of raising silkworms to produce silk. It is a major industry in Telangana, India, and is practiced in parts of the state, particularly in Mahabubnagar district. The district is home to a number of silk farms, which produce silk from the cocoons of silkworms. The silk produced in Mahabubnagar district is known for its high quality and is used to make a variety of products, including sarees, scarves, and shawls.

The other options are incorrect because:

• Coastal districts are not known for sericulture.
• Hilly regions are not suitable for sericulture, as the climate is not conducive to the growth of mulberry trees, which are the main food source of silkworms.
• Areas near major urban centers are not typically associated with sericulture.
