Your answer: —  Â·  Correct: A
Explanation

The classification of the listed animals corresponds to specific biological phyla or classes. Ascaris lumbricoides is a well-known roundworm belonging to the phylum Nematoda [2]. The Malarial parasite, specifically species of the genus Plasmodium, is a unicellular organism classified under the phylum Protozoa [2]. The Housefly (Musca domestica) is an insect, which falls under the phylum Arthropoda, characterized by jointed appendages and an exoskeleton. Finally, the Cow (Bos indicus or Bos taurus) is a vertebrate belonging to the class Mammalia within the phylum Chordata. Matching these pairs (A-3, B-4, C-2, D-1) leads to the sequence 3, 4, 2, 1. This systematic categorization reflects the diversity of life from unicellular parasites to complex multicellular mammals.
