Wilfred's expected utility function is pc^1/2₁ + (1 - p) c^1/2₂, where p is the probability that he consumes c₁ and 1 - p is the probability that he consumes c₂.Wilfred is offered a choice between getting a sure payment of $Z or a lottery in which he receives $2,500 with probability .40 or $6,400 with probability .60.Wilfred will choose the sure payment if

A) Z > 4,624 and the lottery if Z < 4,624.
B) Z > 3,562 and the lottery if Z < 3,562.
C) Z > 5,512 and the lottery if Z < 5,512.
D) Z > 6,400 and the lottery if Z < 6,400.
E) Z > 4,840 and the lottery if Z < 4,840.
