Detailed Explanation:

Answer: Option 4 — textile fibre

The Himalayan nettle (Girardinia diversifolia) is a wild plant native to the Himalayan region that produces some of the longest natural fibres in the plant world, extracted from its stem. These fibres are strong, durable, and biodegradable, making them an excellent sustainable alternative to synthetic textiles and even comparable to flax or hemp fibres. The plant has gained attention in recent years as a source of eco-friendly textile material for the fashion and fabric industry.
