Sexual reproduction is a complex process that involves the fusion of male and female gametes (reproductive cells) to form a new organism. This process is known as fertilization. In fertilization, the sperm cell (male gamete) and the egg cell (female gamete) join together to form a zygote, which then develops into an embryo. The other options are incorrect, as they do not involve the fusion of male and female reproductive cells. Excretion is the removal of waste products from the body, fallout refers to the dispersal of radioactive particles, and fatty acids are essential nutrients found in food. Therefore, the most accurate answer is fertilization.
