本题考查对转学学生常见心理问题的理解。题目核心在于识别转学后可能遇到的主要困扰。关键点在于理解转学生最普遍的担忧是融入新环境，而非年龄、选择或活动量等表面因素。

选项分析

A) Most of her schoolmates are younger than she is.

• 表面现象：同学年龄较小可能影响适应，但题目未提及年龄相关矛盾，且年龄差异并非转学后的主要问题。

B) She simply has no idea what school to transfer to.

• 信息不足：选择学校困难属于转学前的决策问题，而非转学后适应的核心矛盾。

C) There are too many activities for her to cope with.

• 活动压力：活动多可能增加负担，但适应性问题更根本，活动只是外在因素。

D) She worries she won't fit in as a transfer student.

• 核心问题：融入新环境是转学生的普遍挑战，涉及社交关系、自我认同等深层需求，直接对应转学后的主要心理压力。
