Stroma

Chloroplast
Cytoplasm

The correct answer is: Thylakoid membrane

During photosynthesis, the light-dependent reactions take place in the thylakoid membrane. This is where light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH. The thylakoid membrane contains the photosystems I and II where these reactions occur. The stroma (Choice A) is where the light-independent reactions (Calvin cycle) take place, not the light-dependent reactions. The chloroplast (Choice C) is the organelle where photosynthesis occurs, but the specific location for light-dependent reactions is the thylakoid membrane. The cytoplasm (Choice D) is not involved in photosynthesis at all.
