In the most common type of endosperm development in angiosperms, the primary endosperm nucleus (PEN) undergoes repeated nuclear divisions. With reference to this, which of the following statements correctly distinguishes the components of a tender coconut?

1. The coconut water is cellular endosperm, while the surrounding white kernel is free-nuclear endosperm.
2. The coconut water is free-nuclear endosperm containing thousands of nuclei, while the surrounding white kernel is cellular endosperm.
3. Both the coconut water and the white kernel represent free-nuclear endosperm at different stages of maturity.
4. The coconut water is triploid cellular endosperm, whereas the white kernel represents diploid persistent perisperm.
