The correct option is
A Androecium and gynoecium respectively
Aandroecium is the male reproductive organ consisting of units called stamen.
The stamen has two parts:
●Anther - It is bilobed and contains microsporangia. The sporogenous tissues present at the centre of the microsporangium are capable of giving rise to the microspore or pollen grain. From the generative cell of pollen grain male gametes are formed.
●Filament - It is a long and slender stalk which possess anther at the tip.
Gynoecium is the female reproductive organ of flowering plants which consists of units called pistils or carpels.
Pistil has the following parts:
●Ovary - It is the basal swollen part which contains the ovules. Inside the ovule embryo sac with egg is present.
●Stigma - It is the distal bulbous part which acts as the landing platform for pollen grains.
●Style - It is the cylindrical part which connects the ovary with stigma.
