Answer:
C.) Characterization
Explanation:
Characterization is a literary device in which authors reveal a character's personality or gives information about them, whether in a direct form (when the character is "labeled" directly like something) or an indirect form (when the author conveys information about the character by only narrating their actions, desires, preferences or thoughts).
The sentence uses this literary device because the author is indirectly revealing a character's traits and situation by giving information about the narrator (which can also be a character): the internet had made them lost their privacy and independence.
