Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The Myriapoda consists of four classes of terrestrial arthropods (Chilopoda, Diplopoda, Symphyla, and Pauropoda) that share a number of morphological features. However, the status of the Myriapoda as a monophyletic group is controversial.

Detailed explanation-2: -Myriapods. The myriapod body plan is elongated and composed of numerous segments (Figure 3-10). Each segment, except for the head and anal segments, bears either one (centipedes) or two (millipedes) pairs of legs, although the first few segments in millipedes bear only one pair of legs.

Detailed explanation-3: -Myriapods (from Ancient Greek (muríos) ‘ten thousand’, and (poús) ‘foot’) are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13, 000 species, all of them terrestrial.

Detailed explanation-4: -The Myriapods are centipedes and millipedes, and some small relatives. Centipedes and millipedes look similar to each other; they both look a little like worms with lots of legs. Actually they are arthropods, they have a tough exoskeleton and jointed legs, and they are related to insects and crustaceans.
