Answer:
b. a Bengali refugee
Step-by-step explanation:
Peter Albert David Singer AC was a popular Australian moral philosopher. He was well known for his works in Bioethics.
He proposed a theory which states that:
‘We(the affluent) ought to give to the needy until we reach the level of marginal utility-which means that in giving the appropriate amount, we would reduce ourselves to very near the material circumstances of a Bengali refugee’. This simply tells us that we ought to save the lives of strangers when we can do so at relatively little cost to ourselves.
