Answer:
C. Kuno’s prediction and Vashti’s revisiting of the prediction
Step-by-step explanation:
The book "The Machine Stops" is a short story that describes people who live underground and are solely dependent on a machine to solve the physical and spiritual needs.
Vashti is one of the inhabitants along with her son Kuno. Vashti is an obedient follower of the machine and its actions and decisions but Kuno is a rebel who is not happy with the way things are run underground and is eager to leave.
He tries to escape but is caught and forced to stay back, then subsequently he begins to see defects in the Machine and predicts its collapse, Vashti brushes aside his predictions even though they become more glaring each day.
Eventually when the defects become too much, Vashti revistists the prediction of Kuno and begins to brood. This causes suspense and confusion.
