Answer 1

Hint: There are millions of living organisms found in this world. There are some species that are even not discovered yet. we mainly divided the living organisms into animals, plants, microorganisms, etc. All of them have great diversity in their characteristics.

Complete answer:
There are a million numbers of living organisms present on the earth. They are animals, plants, and microorganisms. These organisms have a great diversity in their characteristics.
The animal kingdom is composed of a number of organisms that range from the simplest of the animal forms to the most complex. All the members of the animal kingdom are classified into different groups. Classification of animals is known as Kingdom Animalia. It is further categorized into different phylums. The phylum is a type of division in which animals or organisms with the same characteristics are included under them. Apart from the primary distinguishing characteristics of the animals, each phylum shows that the organisms have common characteristics and they belong to the same phylum.
There is different phylum in the classification of the animal kingdom which are Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Protochordata, and Vertebrata.
In the phylum Porifera, the animals that belong to this group contain pores all over the body, which help to circulate the water throughout the body, which passes food and oxygen.
The animals that belong to the phylum Coelenterata are diploblastic. In this case, the body of the animal is composed of two layers of cells where one-layer forms cells on the outside of the body, and the other layers form the inner lining of the body.
The phylum Annelida is a group of animals that possess metameric segmentation. Metameric segmentation can be defined by a longitudinal division of the body into a similar section of parts. In the phylum of Arthropoda, the animals have characteristics of jointed appendages.
The animals belonging to the phylum Mollusca are soft-bodied animals with bilateral symmetry.
Phylum Echinodermata is a phylum of animals that are spiny-skinned marine animals.
Thus, the right option is A.

Note: All of living organisms have great diversity in their characteristics. Based on their characteristics, they are classified into different groups which are known as a phylum. The animal belongs to the phylum Porifera are pore bearing animals. The animals of the phylum Coelenterata are diploblastic. The animals of phylum Annelida have metameric segmentation. The animals of phylum Arthropoda have jointed legs. The animals of phylum Mollusca are soft-bodied animals. The animals of phylum Echinodermata are spiny-skinned animals.
