The correct option is
D Fruit
Fruits are formed by the maturation of one or more ovary. Fruits contain seeds resulting from the maturation of fertilized
ovules. However, maturation of seed and fruit can occur in the absence of fertilization. In fleshy fruits, the outer covering is called as pericarp. Pericarp is again made of three layers, the epicarp, which is the outermost layer; the mesocarp, which is the middle layer; and the endocarp, which is the inner layer surrounding the ovary or the seeds.
So, the correct answer is option D.
