In which situation would a writer most likely use informal language?

Dialogue or in a personal narrative.

Explanation:

Informal language is used in dialogue to create more depth to a character (a good example is y'all, it connotates the character is from the South). In a personal narrative, a writer may use informal language to describe a feeling/talk about a personal experience. An example could be a writer talking about how they used to called there grandmother "meemaw".
