Legally Blonde (Posted on 2016-12-19) Difficulty: 1 of 5
You meet three blonde women, A, B, and C. Each of them is either a knight or a liar. Exactly one of them is Elle Woods.

A:I am Elle Woods.
B:I am Elle Woods.
C:At least two of us are liars.

What are A, B, and C, and who is Elle Woods?

(In reply to re: Logical Outcome (Spoiler) by Steve Herman)

Due to a symmetry between A and B and knowedge 
(the text) that there is only one EW - there is no way to get a correct answer favoring one or another.

C only determines that there two or three liars. No mention of A or B! Since three liars is out of the question - only two qualify!
Contrary to you - I agree with your reasoning, albeit slower than mine.
Calling it "correct" does not negate the validity of other explanations..
