B.) Oogenesis<br /><br />Polar bodies are formed during the process of oogenesis, which is the development of mature egg cells (ova) in females. They are small haploid cells that contain little cytoplasm and are essentially a byproduct of meiosis, ensuring the ovum retains most of the cytoplasmic nutrients.<br />
