b. chloroplast
Explanation:
Chloroplasts are the double membrane-bound organelles that serve as the site for photosynthesis in eukaryotes. Chloroplasts are the organelles where eukaryotic autotrophs synthesize the organic nutrients by the process of photosynthesis. According to the given information, the first eukaryotic cells were heterotrophs as they derived energy by available organic compounds. They did not synthesize the organic nutrients to use them as fuel. Chloroplasts are not present in heterotrophic organisms such as animals. Therefore, chloroplasts are most likely to have appeared last in the eukaryotic cells.
D: Both are not a mammal, are multicellular, and are heterotrophic
