Answer : The correct answer is -
D.Protista and Eubacteria.
Autotrophs are the organisms that can synthesise their own food using substances available in their surroundings with the help of either chemical energy (chemosynthesis) or light energy (photosynthesis).
Heterotrophs on the other hand, can not synthesise their own food and depend on either plants or animals.
Out of the given options, Protista and Eubacteria conatin autotrophs or heterotrophs.
Example- Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps.
Algae, which is a protist and obtains nutrition through photosythesis.
Slime moulds, which are fungus-like protists and are heterotrophic.
Cyanobacteria (also called blue green alage) is a photosynthetic bacteria (belongs to Eubacteria).
