Which of the following is an example of Crustacea?

Explanation:
Crustaceans are aquatic arthropods typically characterized by having two pairs of antennae and biramous, or branching, limbs, often with gills for breathing in water. A lobster fits this group as a decapod crustacean with a cephalothorax covered by a hard carapace, multiple walking legs, and large claws. Spiders, in contrast, are arachnids with two main body segments and eight legs and no antennae. Butterflies and ants are insects, which have three body segments, one pair of antennae, and usually wings (in the case of butterflies) or a wingless form (in many ants). So a lobster is the clear example of Crustacea.
