Fiduciary Question

In this question, you can pretend you are one of Lyndas children and there is no fiduciary relationship. Let us assume Lynda will buy one of the three Treasury bonds and then bequeath in her will the Treasury bond to her children the children will inherit the Treasury bond when Lynda passes away. Lynda asks the children to select the Treasury bond that will maximize the childrens wealth (not Lyndas wealth). There is a catch where if the children select the wrong Treasury bond, Lynda will bequeath the Treasury bond to their Uncle Bob. Which Treasury bond will maximize the childrens wealth? Explain your answer.
