Genetic Purity Standards for Seed Classes:
- Truthfully Labelled (TL) Seeds: Self-certified by the seed producer without statutory field inspection by a certification agency; maintains variable/lowest formal genetic purity standards.
- Certified Seeds (Blue tag): Produced from foundation seeds, certified by SSCA; statutory genetic purity requirement is typically 99.0%.
- Foundation Seeds (White tag): Progeny of breeder seeds, certified by SSCA; statutory genetic purity requirement is 99.5%.
- Breeder Seeds (Golden yellow tag): Direct progeny of nucleus seeds produced under direct supervision of the sponsoring plant breeder; requires 100.0% absolute genetic purity.
Arranged in ascending order (lowest to highest purity):
$$\text{TL Seeds (A)} \lt \text{Certified Seeds (D)} \lt \text{Foundation Seeds (C)} \lt \text{Breeder Seeds (B)}$$
Therefore, the correct ascending order is (A), (D), (C), (B).
Correct Answer: Option 3.
