Mill's argument from analogy begins with the fact that

A) solipsism is necessarily true.
B) the other's bodily movements and mental states are correlated.
C) your mental states and your bodily movements are correlated.
D) there are no minds, only bodies.

Mill's argument from analogy starts with the observation that one's mental states and bodily movements are always correlated. Based on this, he argues that we can infer that the mental states and bodily movements of others are also correlated, and that therefore, others have minds similar to our own. Therefore, the best choice is C - "your mental states and your bodily movements are correlated."
