What did massey energy's managers order employees to do in the mines that violated federal mining regulations? les 305?

Massey Energy's managers ordered their workers to go into the mines despite the lack of safety inspections. This was a careless act done by the company because they knew the mines were not cleared as safe and they should not have let people go into the mines until they were checked. The company knew that they could persuade the employees to go into the mine because it is a high paying job and the miners are aware of the risks they take before entering into the mine.

Ithink that it’s b but not for sure
