Dogen, Buddhahood, and the recent poll

The results of the latest poll from this website seem interesting enough to serve as a post that might lead to a little discussion.
The poll asked:

"That we will realize Buddhahood..."

A. Must not be doubted. ..............resulting in.........25% of the votes
B. Is what the Buddha taught. ................................25%
C. Is a foregone conclusion..................................... 25%
D. All of the above. ..................................................0%
E. None of the above. .............................................25%

This poll was constructed from a quote of Master Dogen's.... His "answer" (at least in the passage in question) is the only one that recieved 0%

"You must not doubt that you will inevitably realize Buddhahood, for it is a foregone conclusion. It is precisely what the Buddha gave voice to."
~Dogen - Shobogenzo, Kuyō Shobutsu, Rev. Hubert Nearman

Any ideas? Comments?
