The correct option is C.

Explanation of the correct option:

1. A stamen is the part of a flowering plant that is male and contains male gametes.
2. Anther and filaments make up its structure.
3. Anthers build the pollen grains, which are held in the filament by the host plant.
4. Tetradynamous refers to the presence of six stamens (four long and two short), two of which are shorter than the other.
5. Didynamous refers to the presence of four stamens (two long and two short), two of which are of unequal length.
6. Turnip, mustard, and radish are perennial herbaceous plants in the Brassicaceae family.
7. Turnip and Salvia have didynamous and radish and mustard have tetradynamous stamens
8. The length of the stamen varies as a result.
9. Out of ten plants, four have unequal stamen lengths because it has been discovered that the families Brassicaceae and Lamiaceae have different stamen lengths.

Final answer: Turnip, Salvia, mustard, and radish plants have stamens of different lengths in their flower.
