$A$ ruptured follicle in a mammalian ovary,after the release of the ovum,forms:

What is the meaning of oligospermia?

Immediately after ovulation,the mammalian egg is covered by a membrane. What is this membrane called?

The provided image is completely unrelated to the question text. The question asks for a diagrammatic presentation of developing follicle events in the human ovary. Based on the standard biological sequence of ovarian follicle development:
$1$. Primary follicles develop into secondary follicles.
$2$. Secondary follicles develop into tertiary follicles.
$3$. Tertiary follicles develop into the Graafian (mature) follicle.
$4$. After ovulation,the ruptured follicle transforms into the corpus luteum.
Given the standard sequence,identify the correct labels for $C$ and $E$ in a typical diagram of this process.

The Graafian follicle ruptures to release the secondary oocyte (ovum) from the ovary by the process called.....
