I think it is A because I have this question before and I know it already.
The correct answer that would best complete the given statement above would be a myth. Myth is a traditional story about legendary heroes and supernatural beasts. Generally, myths do not have a basis on facts or natural explanation and is often based on one's culture.
The correct answer is B. exploring the imagination and emotions of the individual.
C also can be correct, but if you need to choose just one answer, then I'd rather go with B. Romanticism in general is all about emotions, and the imagination that both the authors and the characters portray in their lives. A is all about Modernism, rather than Romanticism. D and E are all about Enlightenment and Classicism, rather than Romanticism.
Ok, if you're gonna ask something please make it understandble.
