问题：

[单选题]The sequence {2, 7, 13, 5, 3, 19, 17} is obtained after one insertion in the insertion order, and the sorted portion has 3 elements. After 2 iterations, the result is插入排序中的某一次插入后得到序列{2, 7, 13, 5, 3, 19, 17}，此时已排序部分有3个元素。又经过2趟迭代后的结果是：
A{2, 3, 5, 7, 13, 17, 19}
B{2, 3, 5, 7, 13, 19, 17}
C{2, 5, 7, 3, 13, 19, 17}
D{2, 3, 5, 13, 7, 17, 19}
