According to the passage, which of the following options would constitute as an appropriate snack to eat on the go?

According to the passage, a protein bar would constitute as an appropriate snack to eat on the go. The passage\u2019s last sentence states that the better approach is to pack a snack that contains protein and fiber, both of which would be found in a protein bar. The other options can be easily eliminated, as they would not contain the passage\u2019s suggested protein and fiber contents.
