उत्तर और व्याख्या · explanation in English
Answer: (d) यह वस्त्रतंतु का संधारणीय स्रोत है

- ✓ (d) The bast fibre of its bark is used for clothing, ropes, mats and sacks, and the Ministry of Textiles has supported research on products from Himalayan nettle among natural fibres.
- ✗ (a) Anti-malarial drugs come from plants like cinchona (quinine) and Artemisia (artemisinin), not from Himalayan nettle.
- ✗ (b) Biodiesel comes from oil-bearing seeds such as jatropha and pongamia; nettle is valued for its fibre, not for oil.
Remember · Himalayan nettle (Girardinia diversifolia, 'bichhu buti') yields bast fibre for textiles; Uttarakhand and the Ministry of Textiles have promoted it.
