if you say celia's statement is true this mean she can not be last

Next we have Ana, if her statement is false this means that she has to be the oldest so she is first

then we come to Beatriz if her statement is false this mean she has to be the youngest so she is last

The order follows as ACB, I think this does not break any rules. So i think this is the correct order Correct me if i'm wrong!
