To study the types of animals with respect to the presence or absence of body cavities, we need to compare two groups: A and B.

A) Molluscs and B) Chordates

Molluscs are a diverse group of animals that include snails, clams, and octopuses. They have a well-developed body cavity called a coelom, which is a fluid-filled space that surrounds their internal organs.

Chordates, on the other hand, are a group of animals that includes vertebrates like fish, birds, and mammals. They also have a body cavity called a coelom, which is important for the protection and support of their internal organs.

So, the correct answer is A) Molluscs and B) Chordates.
