A)Na⁺ channels have much greater diversity than K⁺ channels.
B)Typically,a more complex nervous system also contains a greater diversity of channels.
C)There is a great diversity of channels,but within a single organism,only one isoform of a channel can exist.
D)There is a large diversity of channels,but they show no physiological significance.

Typically, a more complex nervous system (e.g. in higher animals) contains a greater diversity of voltage-gated ion channels. This is because different channels can perform various functions in different parts of the nervous system. For example, some channels might be specialized for fast signaling in axons, whereas others are better suited for fine-tuning the activity of synapses. However, there is still a considerable diversity of channels even in simpler organisms.
