Solution

The correct option is D Asteraceae
Stamen is the reproductive organ of the flower that produces the pollens. It typically consists of a stalk or filament and an anther. The stamens of the flower are collectively called as androecium. Mostly the anthers are two-lobed and are attached to the filament either at the base or in the middle portion. Depending on the species of the plant there are variations in the morphology of the stamens. A situation where the anthers are fused together into a tubular structure and the filaments are free is called as synandrous and is a feature of the family Asteraceae.
Therefore, the correct answer is option D.
