Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.
