A strategy we use to make inferences about characters is

cation

O setting + assumptions

make generalizations made about types of people

textual evidence + prior knowledge + human nature

only use direct characterization to understand characters

The best option to make inferences about characters is:

Textual evidence + prior knowledge + human nature

Explanation:

An inference is a conclusion based on some evidence and reasoning.

Evidence in making inferences about characters is textual evidence, and reasoning is prior knowledge + human nature.

Prior knowledge is everything we have learned. For example in this case, it could be how a King behaves, how he should be, how people of certain race, geography or ethnic group behave etc., what are their characteristics, how people in specific situations and conditions behave (e. g colonized people) - all this is part of our prior knowledge. Knowledge about human nature (this too is part of prior knowledge) is also considered while making inferences about characters.

Setting + assumption is not a correct strategy because although setting influences a character (not to much extent) but assumption is never allowed for making an inference.

Making generalization is also a wrong strategy because generalization are hardly correct.

Using direct characterization and eliminating textual evidence, prior knowledge will also lead to reaching a wrong inference.
