Photosynthetic autotrophs are organisms that are commonly called producers since they can create their own food. They can do that because they have an organelle which is responsible for photosynthesis. Photosynthesis is the process of conversion of carbon dioxide into carbohydrates and other complex molecules. Among the four choices, only the group of animals do not have the capacity to photosynthesize. All plants have are photosynthetic autotrophs. Not all protists and prokaryotes are photosynthetic autotrophs.
Therefore the answer is number 5. Plants, protists and prokaryotes contain organisms that can do photosynthesis.
