The answer is option d) Both A and B
When joining two independent sentences to form a compound one, we may count on punctuation and conjunctions. Option A uses both, a comma and the conjunction "and" to establish the connection between the sentences. Option B does the same by using a semicolon to show the sentences are closely related. Option C, even though very similar to option A, uses unnecessary punctuation: the semicolon should not be used before the conjunction "and" in this case.
The answer is B. The setting becomes more dangerous and unsettling
