Which statement is true for millipedes (Class Diploda)?

Millipedes have a two-part body plan: a distinct head and a long trunk. This head-and-trunk organization sets them apart from many other arthropods and is a defining feature of Diplopoda. In the trunk, many segments are fused in pairs to form diplosegments, and each such segment typically bears two pairs of legs, not one. That combination—two body regions and paired legs across the trunk—is what makes the statement true. They do not have wings and they do not breathe through gills; respiration occurs via a network of tracheal tubes connected to spiracles along the body.
