Answer:
The correct answer is - to produce more pollen grains.
Explanation:
The maturity of the Pinus sp. male cones takes place before the female cones which are due to ensure that there are more pollen grains available. The higher the number of pollen grains is better for surrounding the female cones when it matures.
This helps in pollination to be species-specific rather than pollinate by any other flower. This feature of early maturation result in easy pollination of the Pinus species.
