I think the answer is characterization (I originally said plot but I just realized that I made a mistake when I was reading. Sorry about that! Hope I didn't mess anything up for you.) :D
In this passage from “The Wedding Night”, the author uses “vivid description” to develop the characters. So, option D) is the correct one.
Throughout the passage, there are several examples that reinforce the use of vivid descriptions such as “a sort of infinite intoxication which comes from the stars, the moon, the silver, glistening water”, “They are a glimpse of a different existence, an embellished, delicious existence”, “The night was magnificent, one of those nights which bring grand, vague ideas to the soul”.
Vivid descriptions are literary resources used to describe emotions and memories in a very clear and detailed way so that the reader produces those vivid images of the descriptions.
Option C does not apply to this part of the excerpt as there are no dialogues introduced. As regards direct and indirect characterization, the author is not describing the character’s personality through these literary resources.
