Which of the following statements BEST explains why double fertilization is advantageous for angiosperms?
It ensures the formation of a triploid endosperm, which is more resistant to pathogens.
It allows for the production of both seeds and fruits, enhancing dispersal.
It synchronizes endosperm development with embryo development, preventing wasted resources if fertilization fails.
It eliminates the need for separate male and female gametophytes.
