Detailed explanation-1: -Anther: The part of the stamen where pollen is produced.

Detailed explanation-2: -stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip.

Detailed explanation-3: -Male reproductive parts are known as stamens or androecium which produce pollen grains. Two parts of the androecium are anther and filament. The stalk is known as filament, and the swollen top is called anther.

Detailed explanation-4: -Pollen is produced and stored in the anther of the flower. A male plant has a stamen that supports the anther and is often referred to as pollen producing as well. The filament attaches the anther to the flower. The petal of a flower is what attracts insects and animals to the plant.

Detailed explanation-5: -The proximal ends of the filament are found attached to thalamus or petals while the distal end carries anther which makes option D correct.
