}
B) for (int item : items) { cout <<items[item] <<endl;
}
C) for (int item : items) { cout <<item <<endl;
}
D) for (int item : items.size()){ cout <<item <<endl;

The range-based for loop is used to iterate through each element of the array, so option C correctly uses the for loop to display each element of the array named "items." Option A uses the traditional for loop method that also works, but may be less readable than the range-based loop. Option B tries to access the element of the array using the loop variable "item" as an index; this will fail because the loop variable already contains the element value itself. Option D tries to use the size of the array as an iterator, which is not valid syntax.
