I would say the correct answer is C. glorify God through work; wealth is a sign of success at work; refrain from self-indulgence. Protestant ethic doesn't claim that wealth is evil. According to it, wealth is a consequence of hard work and frugality, and therefore, in the hands of an honest person, wealth is a blessing. A person mustn't spend time in idleness when they could be working and earning money. Of course, this concept shouldn't be understood as greed. It's not for the sake of accumulating money that a person should work hard; it's for the sake of living a dignified life and doing good to other people.
