Photosynthetic Protista involve mainly three phylum: Pyrrophyta, Diatoms and Euglenoids. They shows myxotrophic nutrition. Some are photoautotrophic, some are saprobic and some are holozoic (who capture and ingest their prey). Photoautotrophic members have long radiating chloroplast. Chloroplast contains chlorophyll a, chlorophyll b, beta-carotene and xanthophyll. With the help of chlorophyll and sunlight they synthesize their food.
Hydra belongs to phylum Coelentrata of animals and is heterotrophic.
Paramecium is a protozoan which again are primitive animals with no pigment for photosynthesis.
Monocystis is an endoparasite of earthworms.

The correct answer is option B, Euglena.
Explanation:
Heterotrophic organisms are those that rely on consuming other organisms or organic matter for obtaining their nutrition. On the other hand, autotrophic organisms are capable of synthesizing their own food using inorganic compounds such as carbon dioxide and water through photosynthesis.
However, Euglena is a unique organism that possesses characteristics of both autotrophs and heterotrophs. It is a photosynthetic organism that can produce its own food through photosynthesis, like autotrophs. It contains chloroplasts that help in the synthesis of food.
But, in the absence of sunlight, Euglena can behave like a heterotroph and can feed on other organisms or organic matter to sustain itself. It can engulf other organisms using its flagella and consume them.
Therefore, Euglena is an example of a heterotrophic organism that can synthesize its own food when required.
