Why Correct: Tasar silk, also called tussar silk, is produced by the larvae of the moth Antheraea mylitta, which feeds on oak and other forest trees.
Distractor Analysis: Bombyx mori is the domesticated silkworm that produces mulberry silk, the most common commercial silk. Philosomia ricini, now called Samia ricini, is the eri silkworm that produces eri silk. Antheraea assamensis, also called muga silkworm, produces muga silk, a golden-yellow silk native to Assam.
Takeaway: India produces four main types of natural silk: mulberry, tasar, eri, and muga, with tasar being wild and coarse-textured.
