## Step 1Arthropods are a group of invertebrate animals that include insects, arachnids, myriapods, and crustaceans. They are characterized by having an exoskeleton, which is a hard outer covering that provides both support and protection.## Step 2The exoskeleton of arthropods is not made of bone, but rather a substance called chitin. Chitin is a long-chain polymer of a nitrogen-containing sugar, which is similar to cellulose in plants.## Step 3Given the options, the one that best describes the arthropod skeleton is the one that mentions a hard exoskeleton made of chitin.
