Which of the following is a characteristic of a Certification Sample?

A Certification Sample is specifically characterized by being drawn by a certifying agency or enforcement officer. This process is crucial for ensuring that the seeds meet the legal standards outlined in seed laws, which are designed to promote seed quality, purity, and germination rates. The involvement of a certifying agency ensures that there is an authoritative body overseeing the collection and testing of seed samples, thus providing credibility and compliance with regulatory standards.

The other choices, while they may represent aspects of seed testing or regulation, do not define the unique nature of a Certification Sample. For instance, samples drawn for compliance with seed law or those designed for individual testing might not involve an agency or officer, which is fundamental to the certification process. Similarly, while noxious weed examination is related to seed inspection, it doesn't specifically pertain to the characteristics that designate a sample as a Certification Sample.
