Correct answer
A. Salvia and mustard
Step-by-step solution
According to the morphology of flowering plants, the androecium consists of stamens, each having a stalk called a filament and an anther.
In some plants, the length of the filaments varies within a single flower.
In mustard, there are six stamens, out of which two outer stamens are shorter and four inner stamens are longer, representing the tetradynamous condition.
In Salvia, there are four stamens, out of which two are long and two are short, representing the didynamous condition.
Therefore, Salvia and mustard exhibit variation in the length of filaments within a single flower.
