Hint: Placenta is a specialized tissue, which essentially joins the ovules to the ovary. Placentation in botany, is the term coined to define the way ovules and developing seeds are arranged, attached to the plant's ovary.

Complete answer: In the superficial type of placentation, the ovules are borne on in a multicarpellary, multilocular ovary. The ovules arise from the surface of the septa in this type of placentation and develop throughout the circumference of the inner surface of the partitioning wall. This type of placentation is found in the family Nymphaeaceae. A prominent member of the family Nymphaeaceae, exhibiting superficial placentation is Nymphea (water lily).

So, the correct answer is option C. Superficial.

Note: In angiosperms, ovules are present inside the ovary, and different species have different kinds of placentation. Apart from superficial placentation, there are other patterns of placentation in angiosperms namely, axile placentation, marginal placentation, parietal placentation, and basal placentation.
