Answer:
First option
Step-by-step explanation:
The use of the world marveled is what makes the whole difference, this word means to be filled with astonishment or wonder, which definitely tell how amazed the narrator is.
Why isn’t it the other 3? Well, they don’t quite fit the requirements. Puzzled means confused, respected doesn’t exactly convey emotion of amazement and gawked is a more awkward kind of action, thus meaning that marveled would be the perfect fit.
Have a nice day!
