Answer:
B. ova
Step-by-step explanation:
The egg (also known as egg, ova, oocyte, oocyte or female gamete) is the female sex cell, haploid (n), formed after meiosis of an ovogen, during the process called ovogenesis, which after being fertilized by the male gamete , the sperm (n), during the process of sexual reproduction, generates the diploid zygote (2n).
Morphologically, they are round cells, the largest in the body, unable to move, and their transport to the fallopian tubes (the place where fertilization occurs in humans) occurs through the movements of the cilia present in the cells that line these channels.
