Which one of the following combinations of events represents the correct sequence during reproduction in flowering plants ?

In flowering plants, the reproductive process follows a specific biological sequence after fertilization. The transformations occur as follows:

• Egg → Zygote: Fertilization occurs when a male gamete fuses with the female gamete (egg), resulting in a diploid zygote.
• Zygote → Embryo: The zygote undergoes mitotic divisions to develop into an embryo, which contains the potential for a new plant.
• Ovule → Seed: After fertilization, the ovule develops a tough coat and transforms into a seed, which houses the embryo and stored food.
• Ovary → Fruit: The ovary matures and ripens into a fruit, which serves to protect the seeds and aid in their dispersal.

Option D correctly identifies these developmental stages in the life cycle of an angiosperm as per standard biological principles.
