Following statements are regarding to gastrulation in chick embryo.
A.
During gastrulation, future mesodermal and endodermal cells migrate from the
epiblast through the primitive streak into the interior of the blastoderm.
B.
An aggregation of cells, known as Hensen’s node, forms at the posterior end of
the streak.
C.
As the streak extends, cells of the epiblast move toward the primitive streak,
through it, and then outward again underneath the surface to give rise
internally to the mesoderm and endoderm, the latter displacing a lower layer of
cells called the endoblast.
D.
Cells that remain in the epiblast form the endoderm.

Nitrite reductase will convert nitrite to ammonium. There are two types of nitrite reductase characteristics given below;
a) Both nitrite reductase consist of a single 63kD polypeptide
b) In leaf chloroplasts and root plastids contain different forms of the nitrite reductase enzyme
c) In shoot nitrite reductase directly dependent on the light reaction by the ferredoxin, it activates nitrite reductase in choloroplast
d) NADPH in the roots is provided by pentose phosphate pathway, it also activate nitrite reductase in the plastids
Which of the correct statement about nitrite reductase characteristics?
