I would say the most logical one to put in a fictional narrative would be the second one about the sun mocking the moon. personification is seen usually in fictional works, so it would make more sense :) hope this helps!
The answer is tragically.
Because in a summary you should use as <em>few</em> details as possible, and saying tragically horrible is too many details for one sentence.
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
The rain fell, the sun shone, and the flowers began to bloom is the right answer because each phrase in that sentence is written in the same structure. Hope this helped!
