Answer : c
Hints & Solutions
(c) Papaya is a dioecious plant in which male and female flowers are produced on two separate plants. Hence it prevents both autogamy as well as geitonogamy. Castor and Maize are monoecious and unisexual. Wheat is monoecious and bisexual. Papayas can be dioecious (male and female flowers on different plants), monoecious (separate male and female flowers on the same plant) or exhibit both male and female flower parts on the same flower.
