The discovery of Oak flora in 1966 added a new chapter to the history of Indian Sericulture. Which one of the following states is the leading producer of Oak tasar silk?

Answer: (c) Manipur

Manipur leads oak tasar production (Antheraea proylei, developed 1960s–70s).

Why the others are wrong

(a) Assam is famous for muga and eri silk, not oak tasar.

(b) Bihar (with Jharkhand) is famous for tropical tasar, not oak tasar.

(d) Odisha produces tropical tasar.

The trap

Assam is the famous silk State — but for muga and eri.
