None of the above. Echinoderm refers to a member of the animal phyla Echinodermata, the sister taxon to our own phyla, Chordata.
All mollusks possess a soft body covered by a hard shell, a muscular foot for movement, and a mantle that secretes the shell. These characteristics distinguish mollusks from other phyla in the animal kingdom.
No, a kingdom is the broadest classification group used in biological taxonomy. It consists of multiple phyla, which are further divided into classes, orders, families, genera, and species. Each phylum contains organisms that share certain fundamental characteristics that distinguish them from organisms in other phyla within the same kingdom.

The kingdom of organisms that exhibit characteristics from various phyla is the kingdom Animalia. Animals encompass a wide range of phyla with diverse characteristics, such as chordates, arthropods, and mollusks, among others. This diversity is a key feature of the animal kingdom.

Organisms are grouped into different phyla based on their shared anatomical, developmental, and genetic characteristics. These characteristics include body plan, symmetry, presence of certain tissues, and genetic relationships. Organisms within the same phylum are more closely related to each other than to organisms in different phyla.
A phylum is a major taxonomic rank in biological classification. It is used to group organisms based on shared characteristics and is below kingdom and above class in the hierarchy. Organisms within the same phylum share a set of common features that distinguish them from organisms in other phyla.
Sponge phyla primarily include Porifera, which contains various classes and species of sponges. Other members of the animal kingdom that are related to sponges, albeit not within the same phylum, include members of phyla such as Cnidaria, which includes jellyfish and corals, and Ctenophora, known as comb jellies. Both of these phyla share some primitive characteristics with sponges but are distinct groups with their own unique features.
In the Linnaeus system, organisms within the same class contain similar phyla. Classes are one taxonomic rank above phyla and encompass groups of organisms that share similar characteristics and evolutionary relationships.
Related phyla are grouped into the same kingdom. In biological classification, kingdoms represent a higher taxonomic rank that encompasses multiple phyla that share fundamental characteristics and evolutionary traits. For example, the Animalia kingdom includes various phyla such as Chordata and Arthropoda, which exhibit distinct but related features.
Phyla are determined by major anatomical features. Does the organism have a spine? Is there a skeleton, and if so is it internal or external? Does it have a shell? Is it motile or sessile? Does it conduct photosynthesis? How many limbs does it have? Does it have hair? Does it have feathers? Does it have eyes? And so forth.
