In ICSI, only one sperm cell is directly injected into the cytoplasm of the ovum to ensure fertilization. This is typically done in cases of male factor infertility where the sperm count, motility, and/or quality are low and natural fertilization is unlikely to occur. By directly injecting a single sperm into the ovum, the chances of successful fertilization and subsequent embryo development increase. Hence, option 1 is the correct answer.
