What is the name of the structure formed after the rupture of the Graafian follicle?

Which cells provide nutrition to the germ cells in the seminiferous tubules?

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.
