Correct Option
(A) Assam is the leading producer of Oak Tasar silk in India. This specific variety of silk is produced by silkworms that feed primarily on oak tree leaves. This distinguishes it from tropical Tasar silk, which is derived from silkworms feeding on host plants such as Asna (Terminalia tomentosa) and Arjun (Terminalia arjuna). The ecological and climatic conditions found in Assam and the broader Northeast Indian region are highly favourable for the rearing of Oak Tasar silkworms. The Central Silk Board recognizes Assam as the foremost state in Oak Tasar silk production, with the discovery in 1966 playing a crucial role in the development and expansion of oak silkworm strains in the area.
Incorrect Options
Bihar and Orissa are known for their production of tropical Tasar silk, rather than Oak Tasar. While Manipur also contributes to Oak Tasar silk production, it is not the leading state in this category. These states do not hold the primary position for Oak Tasar silk production in India.
