It is indeed the latter. I did not do a complicated limit to get this answer (68%), rather you should utilize some properties of the binomial distribution.

I'm inclined to think she just lies once about the whole thing. Otherwise, any part of the question could get a random answer, and it really doesn't matter what you ask. You are correct about this.
