Which aspect of a novel most likely has little effect on character development and plot?

The antagonist
The conflict
The point of view
The setting

The POV hope this helps :) (Im not totally sure, but yeah, maybe it's setting?)

the apollo program, also known as project apollo, was the third united states human spaceflight program carried out by the national aeronautics and space administration (nasa), which succeeded in landing the first humans on the moon from 1969 to 1972.
