Which narrator has the ability to know and tell all, including inner thoughts and feelings of characters?

The omniscient narrator possesses the unique ability to know everything about the characters and events within a story. This narrator can delve into the inner thoughts, emotions, and motivations of all the characters, providing a comprehensive perspective that allows for a deeper understanding of the narrative as a whole. This capability enables readers to gain insights into characters' internal struggles, desires, and conflicts, while also presenting a broader view of the story’s setting and circumstances.

In contrast, a first-person narrator only provides a subjective view of events and experiences from their personal perspective, lacking insight into other characters’ thoughts and feelings. A limited narrator focuses on one character’s experiences and thoughts, providing a narrower view of the story. An unreliable narrator, on the other hand, may distort or misrepresent the truth based on their biases or lack of information, which can lead to confusion about their inner thoughts or those of other characters. Thus, the omniscient narrator is distinct in its all-knowing capacity, making it the correct answer.
