Personification.

Explanation:

Personification is the literary technique of giving human attributes and characteristics to a non-living entity. This means that non-living things, ideas, and even feelings are given characteristics of living things like being able to talk or walk or even think.

The given phrase is taken from Ayn Rand's dystopian novella "Anthem", part seven. The narrator reveals that "[they were] walking to the fangs awaiting us somewhere among the great, silent trees". Here, the author makes the trees seem alive, ready to devour them, with its fangs.

Thus, the correct answer is personification.

both the address and the poster use diction to convey their message. diction is defined as a style of writing or speaking based on the types of words chosen in order to send a message. parallelism is when a similar sentence structure is used for several sentences on a text; roosevelt's address doesn't follow that. repetition has to do with repeating a word or sentence in order to emphasize and idea, however neither the poster nor the address use repetion. finally, the address doesn't use images to convey a message.
