B). Hasty generalizations give an impression of something that isn't grounded in fact.
Explanation:
Hasty generalization exemplifies a type of logical fallacy(a flaw in reasoning) that implies as the title suggests impetuous and defective conclusions or arguments based on deficient evidence. Such generalizations are the consequence of ignoring some variables(or considering limited variables or evidence) while determining a conclusion or generalization which leaves the scope for error or fault and therefore, it is often regarded as 'inductive generalization'(broad conclusions based on certain specified examples or variables).
As per the question, Such generalizations propose 'an impression to the readers that something(conclusion or argument) that isn't based on facts or grounded on insufficient facts or evidences'. Thus, <u>option B</u> is the correct answer.
I feel like agree with (B) much more because in the question it states that the quote has to show the "cultural complexity" of the genre meaning that its not as static as it was before as mentioned in question A. , but how it evolved over-time thus becoming more complex : branching out into different ideas of race and class .
