During a field expedition in a region with a varied ecosystem, a group of 1st-year high school students observed different types of animals and their environments. When they came across a set of aquatic organisms, they noticed the presence of lobsters and fish. While trying to classify the observed animals, a student remembered their Biology classes and pointed out that the presence or absence of an internal skeleton could be an important distinguishing criterion. Based on this context and knowledge of animal anatomy and classification, how could the student use the characteristics of the skeletons of lobsters and fish to correctly classify them as invertebrates and vertebrates, respectively?

The student can classify lobsters as vertebrates and fish as invertebrates, since lobsters have a bony internal skeleton, similar to fish.

The student can correctly classify lobsters as invertebrates and fish as vertebrates, based on the presence of an exoskeleton in lobsters and an internal skeleton in fish.

The student can correctly classify fish as invertebrates and lobsters as vertebrates, as fish have an exoskeleton like lobsters.

The student cannot use the presence or absence of a skeleton to distinguish between lobsters and fish, as both groups are vertebrates and have an internal skeleton.

The student can classify fish and lobsters as invertebrates, as both groups do not have support structures, such as an internal skeleton or exoskeleton.
