Reduction reaction (NO2 to NH3) for nitrate assimilation by enzyme nitrite reductase takes place in

Answer: Option C

Reduction reaction (NO₂ to NH₃) for nitrate assimilation by enzyme nitrite reductase takes place in Chloroplast.
In photosynthetic eukaryotes, nitrate assimilation is performed by two transport and two reduction steps: the first nitrate is transported into the cell, then a cytosolic Nitrate reductase (NR) catalyzes nitrate reduction nitrite, which subsequently is transported into the chloroplast, where the enzyme Nitrite reductase catalyzes its reduction to ammonium.
