The correct answer is option D, that is, mitochondria and chloroplasts.
Mitochondria and chloroplasts are the two organelles witnessed in the eukaryotic cells. The majority of eukaryotic cells exhibit mitochondria, while chloroplasts are only found in plants.
Apart from the nucleus, mitochondria and chloroplasts are the only organelles that comprise their own genetic material. They both possess their own DNA, and therefore, both the organelles utilize their own DNA to generate various enzymes and proteins needed for their normal functioning.
The answer to this question is estuaries or mangrove swamps, which are found in estuary environments. Estuaries are the transition between fresh water rivers and the ocean, and the salinity of estuaries change dramatically depending on the relative dominance between the fresh water and marine environments. These are euryhaline species that can tolerate a wide range of salinities, and include mangrove swamp and certain fishes.
