解答：

为了让校长人数最多，假设这段时间的第一年是某位校长任期的最后一年。

接着可以有 $2$ 位校长完成接下来的 $6$ 年，然后再有一位校长任最后一年。

总共是 $4$ 位校长。

所以正确答案是 C。

To maximize the number of principals, assume that the first year of this period is the final year of some principal's term.

Then, there can be $2$ more principals for $6$ years, followed by another principal who works the final year.

This is $4$ principals.

Thus, C is the correct answer.
