Answer 1

The correct option is D Plasmodium

• Bed bugs are a type of insect parasites that feed on human blood, usually at night.
  
• Lice are obligate parasites, living externally on warm-blooded hosts which include every species of bird and mammal. Lice are vectors of diseases such as typhus.
• Mites are small arthropods. Most species are harmless to humans but a few are associated with allergies or may transmit diseases.
  
• Plasmodium is a genus of unicellular eukaryotes (protozoa) that are obligate parasites of vertebrates and insects.
  
• Bed bug, lice and mites belong to phylum Arthropoda and they are insects which act as extracellular parasites of humans and other animals. Whereas, plasmodium belong to phylum Protozoa and it is an intracellular parasite.
