Solution

The correct option is D Four
Flowers are the site of sexual reproduction in a flowering plant. They are a morphological and embryological marvel. The proximal end of the filament of the stamen is attached to the thalamus or the petal of the flower. The number and length of stamens are variable in flowers of different species. The number varies from 3 to 10 in different species. Also, the size of stamens varies largely in different species. Stamen attached to the petal is called as epipetalous. For example, Brinjal.
Thus, the correct answer is option D.
