The correct options are
A These fruits are not fleshy
B The pericarp or fruit wall is not differentiated into layers
When a single fruit develops from a single ovary of a single flower, it is called a simple fruit. There are two categories of simple fruits—dry and fleshy. Dry fruits are called so because they are not fleshy, and their pericarp (fruit wall) is not distinguished into three layers - the epicarp, mesocarp and endocarp. Fleshy fruits are simple fruits with fleshy pericarp.
