Match List-I with List-II

List-I (Silkworm Type)		List-II (State)
A	Oak Tasar silkworm	I	Jharkhand
B	Muga silkworm	II	Uttarakhand
C	Mulberry silkworm	III	Assam
D	Tropical Tasar silkworm	IV	Karnataka

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)

Hint:

To solve this quickly, use two well-known geographical associations:
- Muga silk is endemic to Assam (B - III).
- Mulberry silk production is centered in Karnataka (C - IV).
These two links point directly to the correct option.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
India is the only country in the world that produces all five commercial varieties of silk: Mulberry, Tropical Tasar, Oak Tasar, Eri, and Muga.
The production of these different silks is geographically concentrated in specific states based on the distribution of their host plants and local climate conditions.

Step 2: Detailed Explanation:
Let us analyze each silkworm type and its corresponding primary state:
- (A) Oak Tasar silkworm (Antheraea proylei Antheraea yamamai): This temperate silkworm feeds on oak trees (Quercus species).
Its cultivation is concentrated in the sub-Himalayan belt of India, including states like Uttarakhand, Himachal Pradesh, and Jammu & Kashmir. Thus, (A) matches (II).
- (B) Muga silkworm (Antheraea assamensis): This silkworm produces a naturally golden-yellow silk.
It is endemic to the Brahmaputra valley and is closely associated with the culture and economy of Assam. Thus, (B) matches (III).
- (C) Mulberry silkworm (Bombyx mori): This domesticated silkworm feeds exclusively on mulberry leaves (Morus species).
While grown in several states, Karnataka is the largest producer of mulberry silk in India, centered around districts like Mysore and Ramanagara. Thus, (C) matches (IV).
- (D) Tropical Tasar silkworm (Antheraea mylitta): This silkworm feeds on forest trees like Asan (Terminalia tomentosa) and Arjun (Terminalia arjuna).
It is cultivated in the humid forest tracts of central and eastern India, with Jharkhand being the leading producer. Thus, (D) matches (I).
Combining these matches gives: (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
This sequence corresponds to Option (C).

Step 3: Final Answer:
The correct matching sequence is (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
