C is correct. The additional annuity payment substantially increases Blake's income and wealth,which decreases his marginal utility of consumption. As a result, the average loss of marginal utility from any risk taking decreases as his wealth increases. Thus, he requires a lower risk premium and is willing to buy more risky assets. 答案的逻辑没有看明白。为何MU下降会导致required risk premium下降?这不就变成了替代率下降,要求回报率反而下降了吗?
