Answer: (A)

Stamens are the male reproductive part of a flower, it consists of anther and filament. They are of two types:

1. Monadelphous stamens are stamens that are present in one group, all the filaments are attached tother.
2. Diadelphous stamens are stamens that are present in two bundles and filaments are attached together.

Many members of the family Fabaceae commonly have diadelphous stamens. E.g.; Indigofera, Sesbania, Lupinus, Glycyrrhiza, Glycine max, Crotolaria have diadelphous stamens, present in the form of two bundles. The total number of stamens is 10 so one group has 1 stamen while another group has 9 stamens.

So, the correct option is 'Six'
