It looks like B is the answer. It is important to know whether or not the media that you are consuming is biased or has an ulterior motive that you might not be aware of. I hope this helps you.
I think it’s a or c, but I’m leaning more towards a
A. is most fitting for the answer
Answer: Hi! A useful summary of this passage would focus on D (the natural and man-made features of Bali).
Explanation: The paragraph shown isn't exploring enjoyable things to do in Bali. Secondly, descriptions of Bali's buildings, in particular, wouldn't be necessary if they could be summarized along with man-made and non-man-made features of Bali. Finally, some facts about traveling to Bali could be nice, but they are also not essential for summarizing the atmosphere of the landscapes Bali has to offer. Thus, D is the best answer.
I hope that this helps you out! Have a good day! :)
