When the stamens are united by their filaments into one, then it is known as a monadelphous condition. For example, Hibicus.
A(9)+1 indicates a diadelphous condition, that is stamens are united in two bundles of 9 fused and 1 free. For example, Crotalaria.
Polyadelphous flowers are those in which the stamens have united filaments and are fused in two or more groups. For example, Castor, Citrus, Bombax malabarica.
In syngenesious condition, filaments are free and anthers are fused to form a tubular structure around the style. For example, Helianthus annus.
In synandrous condition, stamens are united by both filaments and anthers. It is a characteristic feature of Cucurbita.
Thus, the correct answer is option D.
