In no case shall conductors in cablebus be smaller than which AWG?

Explanation:
Cablebus is designed to carry large currents, so the conductors inside it must be large enough to handle the heat and provide reliable terminations. The rule sets a lower limit on conductor size, making 1/0 AWG the smallest allowed size. That’s why 1/0 is the correct answer. Conductors smaller than that (like 12 or 4 AWG) would violate the minimum, while a larger size (such as 4/0) is allowed, but not the minimum.
