(A) Autogamy is the transfer of pollen grains from the anther to the stigma of the same flower. Geitonogamy is the transfer of pollen grains from the anther of one flower to the stigma of another flower on the same plant. Both of these processes can be prevented in dioecious plants. In dioecious plants,male and female flowers are borne on separate plants. Therefore,neither self-pollination (autogamy) nor pollination between flowers of the same plant (geitonogamy) can occur. Among the given options,$Papaya$ is a dioecious plant,while $Cucumber$,$Maize$,and $Castor$ are monoecious plants.
