Question

which part is included in the body plan of the phylum mollusca? image of a snail a skeletal system segmented body with small feet for locomotion free-floating internal organs a mantle that folds over and can create the shell

Explanation:

Phylum Mollusca is defined by key body plan features including a mantle—a fold of tissue that often secretes the calcium carbonate shell (seen in snails, a mollusk example). They lack a true skeletal system, have unsegmented bodies (not segmented with small feet), and internal organs are not free-floating. Thus, the mantle is the correct included part.

Answer:

a mantle that folds over and can create the shell
