Solution

The correct option is D In the stroma of chloroplast
Photosynthesis takes place in two major steps, light reaction, and dark reaction. The light reactions of photosynthesis occur in the thylakoids of grana present in the chloroplast. Carbon-fixing and the synthesis of glucose, during the dark reaction (light independent process), takes place in the stroma of the chloroplast.
Thus, the correct answer is option 'In the stroma'.
