Solution
The correct option is C Free nuclear endosperm Coconut
The coconut is a fibrous drupe fruit that has fibrous mesocarp and a stony endocarp surrounding the kernel and coconut water.
Coconut water
Primary Endosperm nucleus (PEN) of tender coconut undergoes free nuclear division in which the nuclear division is not followed by cytokinesis and cell wall formation. Multiple free nuclear divisions result in the formation of a free nuclear endosperm with several nuclei.
Milky water of green coconut represents the liquid endosperm with multiple free nuclei and outer white kernel represents the cellular endosperm.
In the cellular endosperm, the division of the nucleus is followed by successive cell wall formation.
