Davina cannot bear to be late for anything. She is particular about how people have to do things "just right" for her to be satisfied. A psychodynamic theorist might suggest that Davina is fixated at what stage of development?

an-al

Explanation:

An-al stage: In psychology, the term "an-al stage" is considered as the second stage in the theory of psychoanalysis which was proposed by a psychologist named Sigmund Freud.

In the an-al stage, a child is focused on getting knowledge of toilet training and starts at the age of eighteen months and lasts through three years of age. It is considered as the "primary erogenous zone" and therefore a child gains pleasure from bowel movement and ladder controlling.

Due to an-al fixation, an individual will either gain an-al-expulsive personality or an-al-retentive personality.

In the question above, Davina is fixated at the an-al stage.
