An author may use dialogue to provide the reader with?

a direct characterization
b indirect characterization
c direct development
d indirect development

Indirect characterization uses a person/character's speech patterns or other forms of appearance to give a look into their personality. In this case, dialogue would be considered a way to indirectly characterize. Direct characterization, on the other hand, uses actual descriptive words and phrases to give a look at how a character will behave, look, or feel.
