Solution
The correct option is B Oviducal mucosa
The embryo develops from the zygote and is the earliest stage of the development of a multicellular organism. It needs nourishment for its growth and development.
After implantation, the function of providing nutrition to the developing zygote is that of the endometrium of the uterus. Endometrium is the inner layer of the uterus into which the developing zygote embeds itself for its further growth and development.
Before implantation, the fertilisation takes place in the oviduct. The oviduct has peg cells in its mucosal layer. These peg cells secrete a nutritive fluid that provides nutrition to the zygote during its initial dividing stages. Hence the mucosa of the oviduct is also capable of providing nutrition to the developing zygote, though it is not the main source of nourishment.
Perimetrium is the serous membrane that provides a partition between the uterus and the abdominal cavity.
Myometrium is the layer of smooth muscle fibres which contract during childbirth to facilitate the passage of the baby outside the body of the mother.
Ovarian cortex is a part of ovarian stroma. It is composed of connective tissue and contains the ovarian follicles.
