Read the following statements carefully and select the appropriate option given below. (i) It is possible to store pollen grains of a large number of species for years in liquid nitrogen (-196^(@)) . (ii) Cells of the nucellus have abundant reserve food materials. (iii) In a normal flower which opens and exposes the anthers and the stigma, complete autogamy is common. (iv) If both male and female flowers are present on the same plant, it prevents both autogamy and geitonogamy. (v) Cultivation of hybrids has tremendously increased productivity.

Assertion: Wind pollination requires that the pollen grains are light and non-sticky. Reason: Light pollen grains can be transported easily in wind currents.
