Answer:
A. Nicki is a round character; Nicki's father is a flat character.
Explanation:
In fiction, there are different types of characters depending on the performed role, starting with round and flat characters.
A round character has a lot of personality and changes in time. This type of character shows growth and an interesting development during the story and can be more realistic and close to the reader.
A flat character is the opposite: they do not change and tend to be more static and boring to the reader. They usually have a sole trait that never changes in time, and they do not show any kind of development throughout the story.
In the presented passage, Nicki shows signs of growth when she retold her memories as a child with her old fears, comparing them to her actual self. She also shows a realistic side as a character through her dreams and ambitions. On the other hand, her dad clearly shows a flat personality: he is just stubborn and steady, with no further development nor changes. Even Nicki says he never changed and he is the same as always. This is why Nicki is a round character and her father a flat character.
