能解释一下题干和思路吗? 谢谢！

问题如下：

Jun Park, CFA, works at a hedge fund. Most of Park’s colleagues are also CFA charterholders. At an event with recent university graduates, Park comments, “Most CFA charterholders work at hedge funds.”

Park’s remark exhibits which behavioral bias?

选项：

A.

Availability

B.

Conservatism

C.

Framing

解释：

A is correct. Park is extrapolating his observation based on a narrow range of experience (working at a hedge fund that employs many CFA charterholders) to the entire population of CFA charterholders. Using a narrow range of experience is a form of availability bias.
