b. D died more than three years after purchasing the annuity, and D reserved the right to add additional annuitants during W’s life, but D died without exercising the right?

c. The annuity provided that if W died before receiving 120 payments, the remaining payments would be made to D if living, or to X, if D were then dead, but D died while W was alive?
