Solution:
Cotton is the correct answer. There are four types of plant fibres, they are hemp, flax, jute, and cotton. In this, the hemp, flax, and jute are the phloem fibres. Phloem fibre is collected from the phloem part of the stem of certain plants. It supports the conductive cells of the phloem and provides strength to the stem.
While cotton is a cellulosic fibre which is a soft, fluffy staple fiber that grows in a ball, or protective case, around the seed of a cotton plant.
