The correct answer is textile fibre.

Step-by-Step Explanation:

1. Understanding Himalayan Nettle (Girardinia diversifolia):
Himalayan nettle, botanically known as Girardinia diversifolia (commonly referred to as Allo in Nepal and parts of Himalayan India), is a fiber-yielding plant that grows abundantly as a natural weed in the temperate and sub-tropical regions of the Himalayas.

2. Properties of the Fiber:
The stem bark of the Himalayan nettle contains exceptionally long, strong, and durable bast fibers. These fibers are light, smooth, flexible, and possess natural thermal insulation properties, making them suitable for high-quality yarn production.

3. Ecological and Socio-Economic Importance:
Because it grows wildly without requiring synthetic fertilizers, pesticides, or extra agricultural water, it has emerged as a key sustainable and eco-friendly raw material for the textile and garment industry. It provides livelihood opportunities for indigenous communities through eco-textile production (such as jackets, bags, ropes, and garments).

Thus, Himalayan nettle is recognized as a sustainable source of textile fibre.
