问题如下：
The portfolio manager suggested Mary to add some tech-stocks in her portfolio. Mary refused because "I read the newspaper today, it says technology industry suffers high losses last year." Mary most likely exhibits:
选项：
A.Mental accounting
B.Availability bias
C.Framing bias
解释：
B is correct.
考点：资产配置中的行为偏差
解析：Availability bias是一种information-processing bias，人们会采纳一些容易回忆起来的结果。Mary对当天报纸上的观点记忆犹新，容易快速回忆起，所以把这个信息认为是可靠正确的。这就限制了投资机会，并可能使得投资组合分散化不足。
选项C不对吗
