Final answer:
Anheuser-Busch's action is an example of a product recall, which is conducted over safety concerns or defects.
option c is the correct
Step-by-step explanation:
Anheuser-Busch voluntarily taking back packages of their beer because they might contain small pieces of glass is an example of a product recall.
A product recall is a request to return to the maker a batch or an entire production run of a product, usually over safety concerns or product defects that might endanger the consumer or put the maker/seller at risk of legal action.
The instance described does not primarily relate to process improvement, supply chain issues, or voluntary codes of conduct, although these aspects can be interconnected with the recall process.
For example, after a recall, a company may re-evaluate its quality control systems (process improvement), analyze where in the supply chain the defect occurred, and reinforce its commitment to standards and procedures that constitute a voluntary code of conduct.
