In C. elegans , activation of the CED-3 and CED-4 proteins is essential for the apoptosis pathway. In addition, gain-of-function mutations in the ced-9 gene cause its protein to be made in cells that would normally die, resulting in the survival of those cells. Given these facts, which of the following correctly represents the genetic pathway of programmed cell death in C. elegans ?
