Solution

The correct option is A Stroma
When the light hits the chloroplast, the chemiosmotic potential is established by thylakoid membrane. ATP is synthesised through chemiosmosis by transporting protons from the stroma to the lumen. Hence, the lumen becomes acidic compared to the stroma. Stoma will have higher pH compare to lumen.
