Answer: A
In tender coconut the endosperm is initially free nuclear.
Coconut has free-nuclear endosperm: the primary endosperm nucleus divides repeatedly without cell walls, giving thousands of free nuclei suspended in fluid. This is the coconut water of a tender nut. Later, cell walls form from the periphery inwards, producing the cellular white kernel, while the centre stays liquid.
So the endosperm becomes partly cellular only later. Helobial endosperm, where the first division gives two unequal chambers, is typical of monocots such as the Alismatales, not of coconut.
