Solution

The correct option is C Two
A sterile stamen is called staminode.

When stamens are attached to the petals, they are epipetalous as in brinjal, or epiphyllous when attached to the perianth as in the flowers of lily.

The stamens may be united into one bunch or one bundle (monoadelphous) as in china rose, or two bundles (diadelphous) as in pea, or into more than two bundles (polyadelphous) as in citrus.

There may be a variation in the length of filaments within a flower, as in Salvia and mustard.

So, out the given statements only (i) and (iv) are correct.
