Concept:Placentation refers to the arrangement of ovules inside the ovary.
In axile placentation, ovules are attached to a central axis and the ovary is divided into chambers.
Explanation:The diagram shows an ovary that is divided into several chambers by septa.
Inside these chambers, the ovules are arranged around a common central column.
This pattern is clearly axile placentation.
Marginal placentation occurs along one ridge in a single-chambered ovary.
Parietal placentation involves ovules attached to the wall or to peripheral outgrowths.
Basal placentation positions ovules at the base of the ovary.
None of these match the appearance of the illustrated ovary, which has ovules on a central axis.
Therefore, the correct identification is axile placentation.
Answer:C. axile
