In sexual reproduction, the sequence of events typically involves the process of gamete formation, fertilization, and development. The chosen sequence starts with the formation of gametes (B), which are the sperm and egg cells produced through meiosis. The next step is the fertilization (C) process, where the sperm and egg unite to create a zygote. This zygote (A) then undergoes various developmental stages, leading to the formation of a new organism (D).

Understanding this sequence is essential as it illustrates the essential stages in sexual reproduction, emphasizing the role of gametes and the fusion of genetic material to initiate a new life cycle.
