Certification of awareness of product testing typically requires a formal acknowledgment, which is best done through a signed document. While verbally agreeing over the phone or sending an email confirmation may show awareness, a signed document is a more concrete and official way to certify awareness. A training course may also provide information about the product testing, but it does not necessarily certify that the individual is aware of the testing process. Therefore, A is the most accurate and reliable option for certification of awareness.
