Answer:
Option "B & C"
B: One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism.
C: The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics.
Explanation:
One notable difference between gray foxes and island foxes is the small size of island foxes. This character (dwarfism) was exhibited by the common ancestor of all six island fox subspecies. Note that the northern Channel Island fox subspecies are more closely related to each other than to any of the southern subspecies, and that the southern subspecies are more closely related to each other than to the northern subspecies.
