This 15 his obligation to take care of the child.
参考答案: D
参考解析: 照顾好孩子是他的责任。right“权利”,如:You have no right to search my home.你没有权利搜查我家。nature“天性”,如:It is her nature that she trusts people.她很信任他人,天性使然。work“工作”,如:He works for Ministry of Commerce.他在商务部工作。responsibility“责任”,如:Doctors have responsibility to look after their patients.医生有责任照顾好患者。只有responsibility意思上和obligation最接近。
