The correct option is A Surface fibre
Cotton is a part of daily life. Half of the world's textiles today are made of cotton. It is the most important fiber plant in the world. Each "fiber" is produced by the outgrowth of a single epidermal cell. The "fibers" are actually hairs that grow out of the seed coats. Some epidermal cells make long lint hairs. Other cells stop growing before they become too long, we call these fuzz hairs. So, cotton is a surface fibre present on surface of seeds. Thus, option A is correct.
