}
B) for (int i : items) {
System.out.prinf("%d%n", items[i]);
}
C) for (int i : items) {
System.out.prinf("%d%n", i);
}
D) for (int i = 0 : items.length) {

The enhanced for loop syntax is for (type variable : collection). In this case, we want to iterate over the array items, so we use for (int i : items). We then simply print the value of i, which represents each item in the array. Option A is the traditional for loop syntax, which works but is not the enhanced for loop. Option B tries to access the array element using the value of i, rather than using i directly. Option D uses a colon instead of a semicolon to separate the loop variable declaration from the array length, which is a syntax error.
