Which Statement Provides the Most Likely Explanation for the Differing

Which statement provides the most likely explanation for the differing patterns of innervation in arthropod skeletal muscle (polyneuronal) and vertebrate skeletal muscle (single innervation) ?

A) Vertebrates need to modulate muscle force, whereas arthropods always exert the same force with a given muscle.
B) Action potentials in vertebrate neurons are all-or-nothing, whereas arthropod neurons fire action potentials of varying magnitude.
C) Action potentials in arthropod neurons are all-or-nothing, whereas vertebrate neurons fire action potentials of varying magnitude.
D) The two patterns are products of the evolutionary history of the two taxa, and each one allows effective control of muscle contraction.
