To solve this problem, we need to identify the type of placentation where ovules develop on the inner wall of the ovary or in the peripheral part. Let's analyze the options:$\newline \bullet$Basal placentation:$\newline$ - In basal placentation, the ovules are attached to the base of the ovary.$\newline$ - This does not match the description given in the question.$\newline \bullet$Axile placentation:$\newline$ - In axile placentation, the ovules are attached to a central column in a multilocular ovary.$\newline$ - This also does not match the description given in the question.$\newline \bullet$Parietal placentation:$\newline$ - In parietal placentation, the ovules develop on the inner wall of the ovary or in the peripheral part.$\newline$ - This matches the description given in the question.$\newline \bullet$Free central placentation:$\newline$ - In free central placentation, the ovules are attached to a central column that is not connected to the ovary wall.$\newline$ - This does not match the description given in the question.$\newline$Therefore, the correct type of placentation described in the question is parietal placentation.$\newline$This corresponds to Option 3.
