Ineed to pass
read these lines from wilfred owen's "dulce et decorum est."
"in all my dreams, before my sight/ he plunges at me, guttering, choking, drowning."
which of these canbe found in this excerpt?
parallelism
repetition
an epehany
an allusion

The option that can be found in this excerpt is parallelism.
Parallelism refers to sentences in which the same form of words is used throughout. So here, you see the present participle form of the verbs - guttering, choking, drowning - the same form is used in all three verbs.
There is no repetition here - nothing is repeated. There is also no epiphany - it refers to a revelation. There is no allusion - it refers to a reference to something outside the text itself.

Venom, snakes? if that’s what your asking?
