Answer:
The fort looks as though it came out of a storybook, with gun ports along the high wall that faces the sea.
Step-by-step explanation:
In any story or written text about anything, the "setting" is the location, the place or the stage where the events are unfolded, where things happen. Settings provide a sense of a situation's surroundings, be it the geographical location or the time specifics.
Among the given sentences, the only indication of any place/ location is the second sentence where the speaker talks of "the fort". In this sentence, the speaker gave a description of the fort as something akin to a place out of "a storybook, with gun ports along the high wall that faces the sea".
Thus, the correct answer is the second option.
