Answer:
A) The switch in narration increases the proximity of the narrator to the main character.
C) The reader can perceive information only through the filter of a single character.
Step-by-step explanation:
Third person point of view can be either omniscient or limited.
An omniscient third-person point of view occurs when the narrator has an insight into the character's feelings and thoughts. In a limited third-person point of view, the narrator only has an insight into his own thoughts.
Third person point of view provides more information for the readers about the characters. When the narration switches from omniscient to limited, there is a broad spectrum of a situation. The proximity that the narrator has upon the main character is increased, and the narrator can provide information beyond what is known by the main character.
