D Correct answer
Explanation

Bacteria contain photosynthetic pigments in chromatophores, which are infoldings of the cell membrane containing pigments like bacteriochlorophyll. Chloroplasts, chromoplasts, and leucoplasts are types of plastids found in plant and algal cells, not bacteria. Bacteria lack membrane-bound organelles like plastids, so their photosynthetic apparatus is membrane-associated in chromatophores.
