Solution
The correct option is C Amoeba - Leucosolenia - Hydra - Ascaris
- Amoeba is a genus of protozoa and represents the unicellular organisms. Amoeba often called amoeboid, is a type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. However, recent studies have shown that Amoebas do not form a single taxonomic group but are found in every major lineage of eukaryotic organisms.
- Leucosolenia is a genus of calcareous sponges belonging to the family Leucosoleniidae. Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum.
- Hydra is a genus of small, fresh-water animals of the phylum Cnidaria and class Hydrozoa, native to the temperate and tropical regions.
- Ascaris is a genus of parasitic nematode worms known as the "small intestinal roundworms", which is a type of helminth. One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis.
Option C is correct.
