Kevin's answer is good, but I wanted to comment on one small part of it. To me, "contrast to, " in which "contrast" is used as verb, sounds strange. Let me give some examples:
a) In contrast to cats, dogs really aren't that fussy. (This is fine--"contrast" is used here as a noun.)
b) In his lecture, the professor illustrated his point by contrasting cats with dogs. (Fine.)
c) In his lecture, the professor illustrated his point by contrasting cats and dogs. (Acceptable.)
d) In his lecture, the professor illustrated his point by contrasting cats to dogs. (Doesn't sound right.)
I don't know if "contrast to" is outright unidiomatic (though I suspect it is), but I've never heard anyone use it as in d). Has anybody else?
Anyway, even though sometimes you can say "contrast X and Y," in this instance, "contrast X with Y" is clearly preferable, because it makes the distinction clearer. That eliminates C) through E) (which have other problems as well). In B), "that which" is wordy and unnecessary, and "saw to be" unidiomatic. I mean, would you ever say, "I saw him to be a father figure"? No, you would say, "I saw him as a father figure."
The remaining choice is clear and concise.
