Solution
The correct option is C Stromal matrix In
photosynthesis, light independent reactions are known as dark reactions. They
take place in the stromal matrix of chloroplast where all the enzymes required
for the reaction are present. This process does not depend directly on the
presence of light but is dependent on the products of light reaction i.e., ATP
and NADPH. The dark reaction occur through Calvin cycle.
