Answer:
B. Support pro-labor policies that demand better working conditions and wages.
Step-by-step explanation:
Supporting pro-labor policies that demand better working conditions and wages is likely the most effective way to address the issue of poor working conditions and exploitative labor practices in companies like Amazon. Such policies may include minimum wage laws, health and safety regulations, and other protections for workers. By supporting these policies, individuals and groups can advocate for better treatment of workers and ensure that they are able to earn a living wage and work in safe and fair conditions.
