In which cell structure does thevprocess of photosynthesis take place

As we know the process of photosynthesis mainly occurs in plant cells, so we can differentiate between animal and plant cells to see which organelles exist in plant cells, but NOT in animal cells.

The organelles which form that part of the set are

The answer is most definitely chloroplasts as they are the organelles that contain the green pigment chlorophyll which traps sunlight - the energy required to carry out photosynthesis.
