Answer 1

Different organisms belonging to different phyla of the animal kingdom consists of various distinguishing features. These features help in making each phylum unique and pose a variety of functions.

Step by step answer:Pila refers to a group consisting of freshwater snails, belonging to the phylum Mollusca, which consists of predominantly aquatic organisms. The most distinguishing feature of the phylum is the presence of the radula, which is used as a feeding organ, as a rasping organ similar to the tongue to capture food before entering into the esophagus.
-Bombyx is the name for silkmoth and belongs to the phylum Arthropoda, it later develops into a silkworm. The unique feature of the phylum is the presence of Malpighian tubules, which functions as an excretory organ. It can also help in osmoregulation in the organisms. It absorbs solute and water from the hemolymph.
-Pleurobrachia belongs to the phylum Ctenophora mainly known as sea gooseberry. Comb Plates are the distinguishing feature of the phylum and is made of eight rows of cilia, the comb plates are also known as ctenes, hence the name of the phylum. It aids in locomotion.
-Taenia belongs to the phylum Platyhelminthes also known as flatworms, flame cells are the organs present exclusively in the phylum and help in excretion and osmoregulation.
Hence option B is correct.

Note: The different phyla coming under Kingdom Animalia are Porifera, Cnidaria or Coelenterata, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata, Hemichordata, and Chordata. The further classes under Chordata are Aves, Pisces, Amphibia, Reptilia, and Mammalia.
