b) metaphor
c)hyperbole
d)foreshadowing

C) Hyperbole.

Explanation:

Hyperbole is the use of a literary device or figurative language where the writer or speaker uses extreme excess or exaggerated claims to make his point more serious. It evokes a sense of strong feeling, impressions and even more seriousness to the issue that is being discussed.

The lines “200 million cameras track and identify citizens in real time to keep them in line,” is from the article "No Hiding Your Face?" by Joe Bubar for The New York Times Upfront. In this article, he tells how facial recognition had been used to solve crimes and lessen them. But, on the flipside, this technological advancement is also a gross violation of an individual's privacy, which had been protested against by many activists and advocates.

The author Joe uses hyperbole in this use of the word "roughly 200 million cameras" for tracking the every movement of the Chinese people by its government. this is an exaggerated claim which is intended to have a strong impact on the reader, making the issue as something super serious and in need of immediate attention.

there is no short story here so that i can answer the question.
