Explanation:

To determine the correct option, we analyze the Enhanced Fujita Scale table. EF5 has a frequency of 0.02% (the lowest among the options), indicating it is the rarest and most extreme. EF4 has 0.46%, EF2 has 8.41%. Since the question likely pertains to the rarest or most destructive (implied by the options), EF5 (option C) matches the extreme category with the lowest frequency.

Answer:

C. EF5
