Solution:

Stamen is the male reproductive whorl in a flower composed of anther and filament. A filament is a stalk that supports the anther. The anther lobes are connected by a connective that is an extension of the filament. A is the connective. Endothecium is the middle layer out of the three layers in anther that helps in anther dehiscence and pollen grain dispersal. B is endothecium. Pollen grain is the male gametophyte that has the male gametes. c is the pollen grain.
