A library stores a small catalog of book IDs by index. Given the code snippet,

public class Library {
  public static void main(String[] args) {
    // Each index is a shelf position; values are book IDs
    int[] bookIds = {101, 205, 309, 412};

    // Retrieve the third element (index 2)
    int id = bookIds[2];
    System.out.println(id);
  }
}

Which line of code correctly accesses the third element of the array?
