Solution
The correct option is C perisperm
Nucellus is the diploid nutritive tissue present inside the ovule. It usually degenerates after fertilisation and creates space for the development of the embryo and endosperm. But in some plants, nucellus persists in the mature seed even after fertilisation. Such persistent, residual nucellus in the seed is called perisperm. It stores nutrients and nourishes the embryo. Perisperm is found in the seeds of black pepper and beet.
Tegmen - Inner protective layer of the seed.
Chalaza - Region in the ovule where integuments and nucellus merge.
Hilum - Scar on the seed marking its former place of attachment.
