The correct answer is the cause/effect relationship
Explanation:
In the sentence " The roads of New Orleans remained flooded due to the hurricane", the word "due to" shows that the first element "The roads of New Orleans remained flooded" is a consequence of the second element "the hurricane". This means it was the hurricane the one that caused the flood, and in the same way the flood is an effect of the hurricane. In this context, the phrase shows a cause/effect relationship between the flooded roads and the hurricane.
Personification is just taking nonliving objects and making them have living characteristics. Example: The sun's bright smile brought warmth down on the land. This gives the sun human like traits because the sun can't smile. Hope this helps
