Verified step by step guidance

Understand that the arthropod nervous system is characterized by its complexity and efficiency, which is why it is considered well-developed.

Recognize that a key feature of the arthropod nervous system is the presence of a ventral nerve cord, which runs along the belly side of the organism, as opposed to the dorsal side in vertebrates.

Identify that segmented ganglia are another important feature. These are clusters of nerve cells that act as local control centers for each body segment, allowing for more precise and coordinated movements.

Note that the presence of specialized sensory organs, such as compound eyes and antennae, enhances the arthropod's ability to interact with its environment, although this was not mentioned in the options.

Conclude that the combination of a ventral nerve cord and segmented ganglia, along with specialized sensory organs, contributes to the arthropod's advanced nervous system, distinguishing it from simpler organisms.
