The correct answer to the question is:
D) Although
Explanation:
1. The word "although" is used to introduce a contrast between two ideas. In this case, it highlights the contrast between the common class individuals gaining respect from the royal class and the initial lack of respect for surfing in Hawaii.
2. The sentence suggests that even though surfing was not initially held in high regard, some individuals from the common class managed to earn respect from the royal class due to their surfing skills. This indicates a contrast or contradiction in the perception of surfing at that time.
Therefore, option D, "Although," is the most suitable choice to reflect this contrasting relationship between the two aspects mentioned in the sentence.
