The correct answer is: b) Silk and Muga.
Meghalaya is renowned for its intricate weaving of silk and muga. Muga silk is a golden-hued silk produced by the Antheraea assamensis moth, which is found in the forests of Assam and Meghalaya. It is one of the most expensive silks in the world, and is known for its softness, luster, and strength. Muga silk is traditionally used to make saris, scarves, and other garments.
Bamboo and cane are also used in Meghalaya for weaving baskets, mats, and other items. Cotton and flax are not commonly used in Meghalaya for weaving, as the climate is not ideal for growing these crops. Wool and cashmere are also not commonly used in Meghalaya for weaving, as these materials are not native to the region.
