Which person is an example of a flat character? a. a lonely man who discovers his true friends when he has an emergency b. a bank teller who refuses to let the main character complete a transaction c. a spoiled teen who learns to care for people who are less fortunate d. a small, nervous child who grows into a strong and powerful wizard

That would be B, the bank teller. He has no character development and isn't fleshed out, so he's a flat character.

Hope I helped!

A "flat character" is essentially a character who doesn't change throughout a story. They are seen as "stagnant" and remain the same, so it doesn't affect the storyline.

Let's compare this definition to the options you have.

〜 Option a)
A lonely man who discovers his true friends when he has an emergency

ヽ The description we derive from this sentence is that the man is lonely, but eventually discovers his "true friends" when facing an emergency. This change in events means that the character's life has things going on and changes how the man used to be lonely, and instead one may describe him to be surrounded by those who love him; he may be a grateful man rather than a lonely one.

〜 Option b)
A bank teller who refuses to let the main character complete a transaction

Because no further details are given about what happens in the story, we are given the general idea of the bank teller constantly refusing to let the main character complete a transaction. This event is therefore repetitive and constant, meaning the bank teller is an example of a flat character.

〜 Option c)
A spoiled teen who learns to care for people who are less fortunate

The spoiled teen is described to gradually learn to care for the less fortunate, revealing that the character undergoes a change from being ungrateful and careless to being empathetic to those that are less fortunate. This is a change in character and so therefore the spoiled teen in the story is not a flat character.

〜 Option d)
A small, nervous child who grows into a strong and powerful wizard

Because it is said that the child starts off as being "small" and nervous, who then transforms into a strong and powerful wizard, the character's personality stands to represent a kind of oxymoron. This change in persona is a clear indicator of the character being anything but "flat".

Hope this helps! ッ
