In angiosperms, the outer wall of ovary develops into :

Pericarp

The correct answer is Option (2): Pericarp

In the context of plants, an ovary is a plant part responsible for facilitating fertilization and the development of seeds. In most cases, the ovary undergoes a transformation to become the fruit, which aids in seed dispersal. Typically, the ovary is situated at the base of the flower, positioned below the stigma and style. Within the ovary, one or more eggs, known as ovules, are enclosed. The arrangement of these ovules varies among different flower species. Flowers with a single carpel are referred to as monocarpous, while those with two or more fused carpels are termed syncarpous. In contrast, apocarpous flowers have two or more separate carpels.

The structure and function of the ovary in flowers encompass several key components. The outer layer of the ovary is referred to as the ovary wall, which eventually develops into the pericarp, the outer protective covering of the fruit. Inside the ovary, one can find a compartment called the locule, which houses the ovule. The ovule is linked to the placenta, a part of the ovary wall, through a structure known as the funiculus.
