A third-person omniscient point of view is when the narrator knows the feelings/emotions of the character and also knows how the story is structured. A third-person limited point of view is when the narrator knows as much as the reader does, in other words he is "limited" to the knowledge of the reader.
B. An outside narrator relays the inner thoughts of one character in third-person limited point of view but those of more than one character in third-person omniscient point of view.
Third person point of view is when the narrator is outside of the story. This eliminates C and D because if the narrator is talking about his or her own thoughts using I, me, or my, then it would be written in first person point of view. In third person limited, the narrator only tells the thoughts of one character. This is why it's considered limited because the reader is limited to one character's inner thoughts. Omniscient is when the thoughts of more than one character are included.
