Question

The placentation in a multilocular ovary. Where the ovules are borne in the entire inner surface is called:
A. Pendulous
B. Marginal
C. Superficial
D. Parietal

Answer 1

Hint: The female reproductive system of the angiosperms consists of the stigma, the style and the ovary. The ovary consists of many ovules inside it. These ovules are present inside chambers known as the locules. An ovary consisting of many locules is known as a multilocular ovary.

Complete answer:
To know the correct answer to the question, we must be well aware of the different types of ovary.
The female reproductive system in the angiosperm is known as the gynoecium. It consists of the stigma, style and the ovary.
The ovary is the swollen basal part of the pistil or the carpel.
Parietal ovary is the unilocular ovary (in which only one locule is present) where the ovules are present on the periphery. This type of ovary is found in Brassica, Argemone etc.
Marginal ovary is the unilocular ovary in which the ovules are present on the margin. For example: as present in the members of the Family Fabaceae.
Superficial ovary is the unilocular ovary and ovules are present at the base of the ovary. For example: It is found in the members of the Family Asteraceae.
Pendulous ovary is the drooping of the ovules from the ovary.

Since, now we know the various types of the ovary, therefore, the correct answer to the question is superficial ovary.

Note: Here it must be noted that the superficial ovary is polycarpellary and syncarpous. The ovules are found on the inner surface of the ovary. It is the type of the placentation which is found in the members of the Family Nymphaea.
