Solution
The correct option is C Release of pollen grains in prodigious amount
In Pinus, pollination takes place about in March-April in the Eastern Himalayas. Pinus pollens are yellow in colour, winged and are carried by wind. The amount of pollen liberated by the pine forests at this time is prolific, so that air gets saturated with them and there is a yellow deposit of pollens on the forest floor. This phenomenon is known as sulphur shower or flowers of sulphur. Naturally, most of the pollens are wasted and only a small amount reach the female cone for fertilization.So, the correct answer is 'Release of pollen grains in prodigious amount'
