in the last few sentences, it’s mentioned that Manjiro stared at the strangers, meaning he’s curious. Sometimes he caught the barbarians watching him. The similar behavior of curiosity appearing in both parties is what I think is a big giveaway that d is the answer. There isn’t as much proof that the other answer choices are right.
In my opinion is They are just as curious about the fishermen as the fishermen are about them.
Explanation:
The texts says they're rescued then captivated but the sailors haven't done anything to them other than rescuing them from the island.
There is nothing relevant about suspicious creatures in the text.
Nowhere in the provided text there is said that the sailors are gonna do smth bad to the rescued ones. Nor there is a dialog between the sailors about the captives.
Whilst on line 16 till end the sailors and the rescued ppl glance at each other when they think the other one is not looking. Giving the idea of curiosity from both sides. (that's all I could see from the provided text. Hope it helps)
