Answer:
The given statement, "she seems to walk like a dead one since last night," is an example of A. metaphor.
A metaphor is a figure of speech that compares two unrelated things by stating that one thing is another. In this case, the speaker is comparing the way "she" walks to that of a dead person. The comparison suggests that there is a similarity in the way she moves or carries herself to the slow, lifeless movements associated with a dead person.
