You didn't give the options. However, i'll try.
To me, a stone cannot be ethical because it cannot suffer. Indeed, the capacity for suffering must be satisfied before we talk about interest in a meaningful way. For instance, nothing we could possibly do for a stone could make a difference in its welfare. It don't have interest. Whereas, we, humans have interest. Therefore we can be ethical because we are sentient beings that can be benifited or harmed. It's because we can experience pain as a result.
Hope this helps !

It was Crystal Keys first day working in the office. All the staff were really busy this morning. Crystal was asked to miss the induction process to the workplace that most new employees went through. Instead, she was asked to complete a few tasks in the office. Crystal was told the induction would take place after lunch when things settled down a bit. The first task Crystal was asked to complete was to laminate some advertisements. She was unfamiliar with the laminator and managed to melt some plastic sheets on the rollers. This also resulted in her suffering a minor burn w hen trying to remove the plastic. In the process of checking the laminator, Crystal noted that the electrical equipment had not been safety checked in the last 5 years and that the cord was frayed. Next Crystal was asked to change the ink cartridge on th e printer and managed to get black powder everywhere. The office manager became angry about that and sent her to tidy up the stationery room instead. After tripping over some electrical cables that were lying across the walkway, Crystal tried to lift ream s of A4 paper, to get them out of the way. Consequently, she sustained a back strain. Crystal’s first day was miserable and she is not certain she wants to work here anymore.
