难度评级：890

解答：

目标人物左边有 $1013 - 1 = 1012$ 人，右边有 $1010 - 1 = 1009$ 人。包括此人自己，总人数为 $1012 + 1009 + 1 = 2022$ 。

所以正确答案是 B。

The target person has $1013 - 1 = 1012$ people to the left and $1010 - 1 = 1009$ people to the right. Including the person themself, the line has $1012 + 1009 + 1 = 2022$ people.

Thus, the correct answer is B.
