The correct answer is: c) Marketing and export platforms.

Andhra Pradesh has established marketing and export platforms to support the handloom and handicraft sector. These platforms provide a one-stop shop for weavers and artisans to market their products and connect with buyers from around the world. They also provide training and support to help weavers and artisans improve their skills and quality of products.
