In which of the following animal phyla, is the body divided into head, thorax and abdomen ?

Correct option is C

The correct answer is (c) Arthropoda.
 Arthropods are characterized by their segmented bodies, which are typically divided into three main regions: the head, thorax, and abdomen.
 This segmentation is a key feature of the phylum Arthropoda, which includes insects, arachnids, and crustaceans.
 The head usually contains sensory organs and the mouthparts, the thorax bears the legs and wings in insects, and the abdomen contains the digestive and reproductive organs.
Information Booster:
 Annelida: This phylum includes segmented worms like earthworms and leeches. Their bodies are divided into multiple similar segments but not into head, thorax, and abdomen.
 Mollusca: This phylum includes snails, clams, and squids. Mollusks typically have a body divided into three main parts: the head, visceral mass, and foot, but not into head, thorax, and abdomen.
 Chordata: This phylum includes animals with a notochord, such as vertebrates (fish, amphibians, reptiles, birds, and mammals). Vertebrates often have a distinct head, but their body divisions vary widely and do not follow the head, thorax, and abdomen pattern of arthropods.
