Answer 1

Trichinosis is a parasitic disease which caused by roundworms or nematodes trichinella. trichin​​​​osis is called trichinellosis.

Roundworms are the eukaryotic organisms which belongs to phylum aschelminthes of metazoa division of kingdom animalia. Animal kingdom divided in to two division metazoa and protozoa by Ernst Haeckel in 1874. Metazoans are the multicellular eukaryotic organisms while protozoans are single cellular eukaryotic organisms.

So, the option first (1,3 and 5) is the correct option.

Protist are the microscopic single cellular eukaryotes belongs to kingdom protista.

Prokaryotes are microscopic single cell organism without membrane bound cell organelles such as nucleus, mitochondria, golgi body etc.

The lophotrochozoans are trophoblastic protostome animals. Protostome are further divided in to lophotrochozoa and ecdysozoa. Lophotrochozoa includes annelids, logo rates and molluscs while ecdysozoa include arthropods.

So ,the rest options are incorrect for given problem.
