Answer 1

Hint:Animals are multicellular and eukaryotic living beings. Every animal has its own distinct personality. They get their nutrition by eating either plants or other animals. There are millions of species that have been identified; however, only a few have common characteristics, while others have significant differences.

Complete answer:
For us to identify the given organisms we have to carefully observe their morphology and match their characters with the characters of the known phyla under animal kingdom, from there on we can find the genus and more specific details of the organism.

 A. Locusts are the swarming stage of certain short-horned grasshopper species in the Acrididae family. These insects are normally solitary, but as populations increase, they change their behavior and become gregarious. Since locusts eat plants, they do not bite people like mosquitoes or ticks. They are members of the Arthropoda phylum.

B. Scorpions belong to the order Scorpiones, which are predatory arachnids. They have eight legs and can be distinguished by a pair of gripping pincers and a short, segmented tail that sometimes curves forward over the back and often ends in a stinger. Just about a quarter of the 1,500 species of scorpions are capable of killing humans with their stings.

C. Small marine crustaceans with an exoskeleton and ten legs, some of which can be eaten, are known as prawns. A telson is a fan-shaped tail found on prawns and shrimp. They navigate through water by using their tails. They have five sets of legs.

D. Pila is a genus of large freshwater snails with an operculum, also known as African and Asian apple snails, and belongs to the Ampullariidae family of aquatic gastropod molluscs. Apple snails are the common name for this family of freshwater snails. This snail family also includes Pila globosa. Since some species can grow to be the size of apples, they are commonly referred to as apple snails.

Thus the correct answer is option ‘A’.

Note: The word Arthropod comes from the Greek word Arthropoda, which means "worm." Arthopoda is a Greek word that means "joint foot." Arthropods are invertebrate creatures with external skeletons that have joint feet. They lack skin and instead have rigid body surfaces, such as the External Skeleton.
