Explanation:
Arthropods are characterized by the possession of an exoskeleton and a segmented body. This group includes insects, arachnids, myriapods (centipedes and millipeds), and crustaceans.
The Devonian period, belonging to the Paleozoic Era, occurred from around 415 million to 350 million years ago. During this era, arthropods such as centipedes, millipedes, and flightless insects were predominant and diversified throughout this period.
Therefore, as all of these arthropods were present in the Devonian period, the correct answer is <u>d) None of the above</u>.
