Solution
The correct option is C Residual nucellus
Cells enclosed within the ovule are called nucellus. These cells have abundant reserve food materials. After fertilisation the nucellus generally degenerates.
However in some plants the nucellus persists in the seed and it is called perisperm.
Primary endosperm nucleus (PEN) and zygote are formed as a result of triple fusion and syngamy.
