The sentence that uses direct characterization is the following one: Genna observes speed limits because she is a careful driver. That is, the correct option would be C.
Direct characterization means the way an author or another character within a story describes or reveals a character through the use of descriptive adjectives, or phases. That is, direct characterization is straightforward characterization either made by the author or by another character. In this case, the author has made use of the descriptive adjective "careful" to talk about Genna's driving skills.
