Solution
The correct option is D Dhaincha (Sesbania)
Fibers found on the covering of seeds, leaves, or fruits; cotton cloth is made from seed hairs covering the surface of cotton seeds. Few plants have seed or fruit fibers long enough for spinning. Cotton is the notable exception because it produces seed fibers, that can be spun into thread. Seed fibers from milkweed and kapok (Ceiba pentandra, Bombacaceae) are too fine and slippery to spin. These are used primarily as stuffing material and kapok was formerly used for life preserves, because of its lightweight and water resistance and has fibers that trap air. Dhaincha is a short fiber, that can be used as a substitute for hardwood. The flexibility coefficient of Dhaincha is better than hardwood.
