If you want my opinion, all these are a great thing to do.But
However answer B. Would be more reasonable to this question.
The answer is B, as the sentences do not show cause and effect, set up a comparison, or introduce an idea that has already been brought up.
In literature, characterization is the steps that a character in a narrative becomes fully realized or has completed an story arc. It is used to explain the details of a character in fiction. The answer is option B, the strenghts, weaknesses and motivations of the characters.
An example of characterization is when Don Quixote loses his mind after reading too many romances and comes to the realization that he is a knight destined to save his maiden from the forces of the giants (even though we know that he is delusional about the whole thing)
You're answer should be A
Next time remember to choose the correct subject:)
