Answer:
A. Personification -- an object or animal is given human-like characteristics.
Step-by-step explanation:
Personification is a poetical or literary technique that writers use to give life-like attributes to non-human entities. This means that non-animate things are given or presented as living things, given human-like characteristics.
In the poem "Chicago" by Carl Sandburg, the speaker used the poetic device of personification. He describes or presents the cities as living things, "with lifted head, singing" which is a human attribute. He talks of the cities as humans, with a head, capable of singing.
Thus, the correct answer is option A.
