Which narrative perspective allows the reader to see into the thoughts and feelings of all characters?

The narrative perspective that allows the reader to see into the thoughts and feelings of all characters is third-person omniscient. In this perspective, the narrator has an all-encompassing viewpoint and can provide insights into the inner thoughts, emotions, and motivations of multiple characters within the story. This creates a rich and multifaceted understanding of the characters and enhances the reader's engagement with the narrative.

This contrasts with other perspectives, such as first person, where the narrative is limited to the experiences and thoughts of a single character, leading to a more subjective viewpoint. Second person addresses the reader directly, creating a unique immersive experience but typically lacks insight into other characters' internal states. Lastly, third-person limited focuses on the thoughts and feelings of just one character at a time, thus not offering the broader perspective that third-person omniscient provides.
