Cotton is a part of daily life. Half of the world's textiles today are made of cotton. It is the most important fibre plant in the world. Each fibre is produced by the outgrowth of a single epidermal cell. The fibres are actually hairs, that grow out of the seed coats. Some epidermal cells make long lint hairs.
Jute is a bast fibre. Coir is a natural fibre extracted from the husk of coconut.
Banana fibre is a bast fibre.
Thus, the correct answer is option D.
