(A) too high for nuclear power to likely - Split infinitive Error
(B) high enough for nuclear power to be unlikely to - 'to be unlikely to' awkward
(C) high enough that it is unlikely nuclear power will - unlikely nuclear, I think it needs a THAT in b/w
(D) so high that nuclear power is unlikely to - concise and correct
(E) so high as to be unlikely that nuclear power will - 'so high as to be' - awkward

Would it be a good strategy to disqualify a sentence just based on the usage of the above idiom.

Thanks in advance.
