Hint:The term good quality seeds refer to seeds free from diseases, pathogens, and high yielding in nature. Various methods like exclusion, eradication, resistance, biological control, and protection have been applied to ensure good quality seeds. Specialized labs where these conditions are kept constant are sources of good quality seeds.

Complete answer:The good quality seeds ensure the farmer that the crop will give high yield and quality of the harvest. This further ensures good prices in the market. Thus, one needs to select only healthy and viable seeds that are free from diseases and pests. Pests and pathogens like insects, bacteria, fungi, viruses are responsible for the deterioration of the fields. They reduce the quantity as well as the quality of the produce.
The gene banks are places where the seeds, plants, and animals are stored to retain and preserve their genetic diversity. The seed banks are a subdivision of the gene banks. They are specialized to preserve the diverse seed species to preserve their unique genetic constitutions.
Quarantine labs are specialized laboratories. These are specifically designed to exclude, eradicate, protect, and to provide resistance from pests to seeds. One can buy healthy and viable seeds from quarantine labs. They ensure no entry of pathogens or pests that will deteriorate the seed quality. Isolation chambers and proper sanitization ensure the good quality of seeds.

Hence, from the above discussion, it is clear that the right answer is option C.

Note: The inspection of seeds in quarantine labs is done in two methods namely generalized tests and specialized tests. The generalized tests used inspection of dry seeds either with the naked eye or with a high power microscope. This method reveals various free moving insects and their eggs. UV light may also be used for detailed inspection.
