Which of the following is a crustacean?

Crustaceans are a group of arthropods that typically have a hard exoskeleton, jointed limbs, and aquatic respiration (gills), with many species displaying a body plan that includes a cephalothorax and abdomen. Shrimp fit this pattern: they are crustaceans with a segmented body, a protective shell, and multiple paired appendages along with gills for living in water. Beetles, by contrast, are insects with six legs and three body segments; spiders are arachnids with eight legs and two main body sections; worms lack an exoskeleton and jointed limbs entirely. So the crustacean among the listed animals is the shrimp.
