Solution

The correct option is B The pollen grains will germinate.
The viability of pollen grains in some members of Rosaceae, Leguminoseae and Solanaceae is maintained for months. Since rose is a member of the Rosaceae family, its pollen grains will germinate even after a month of their release.
Insects are needed for pollination but not for the germination of pollen grains.
