请问C项不是行为金融的一种吗？那为啥不能选A和B
问题如下图：
选项：
A. 
B. 
C. 
解释：
Gary is a mile-agector. Apart from living expenses, he hseverplans, susave money for travelling after retirement, buy a new house after ten years. He seeks investment aifrom a portfolio manager in AHee Funanrequires to mateaof his plans with fferent portfolio asset allocations. Gary most likely has: loss-aversion bias. bounrationality. mentaccounting bias. C is correct. 考点BPT模型 解析Gary基于目标分别做投资组合，课上说过BPT= gobase= layers = pyrami= mentaccounting bias。所以选mentaccounting是正确的操作，为什么说它是bias呢?（听起来有负面的意思）
有效前沿不才是完全理性吗，分层不是受限制的理性吗？感觉B也对啊。
请问BPT和mentaccounting有区别么？完全一样么？
