Final answer:
The plural of 'ovum' is 'ova,' the term used to refer to multiple egg cells in the field of biology, which also includes processes like oogenesis and ovoviparity.
Step-by-step explanation:
The plural of ovum is c) ova. While 'ovum' refers to a single egg cell, 'ova' is the term used to describe multiple egg cells. In biology, understanding terms like oogenesis, which is the process by which the primary oocytes undergo meiosis to produce the secondary oocyte and, upon fertilization, become the ovum, is essential. Additionally, in the context of animal reproduction, other relevant processes include oviparity, where eggs are laid outside the body, and ovoviparity, a process where fertilized eggs are retained within the female and the young are born fully developed.
