解析 近义词辨析。branch意为“(科学的)分科，分支(机构)”，如：the various branches of learning (各门学科)；sector意为“(经济)部门，部分”，指一个部分或分支，如城市的或国民经济的，如：public sector(国营部门)，private sector of economics(私营经济部门)；portion意为“部分，一份”，特指一份限额或食物的一份，如：He was hungry and ordered two portions of fish．(他饿了，要了两份鱼。)section意为“部分，片断，剖面”，指某物分成几个部分或切割成的几个部分，也可指书籍的章、节等，如：Divide the class into five sections of six students each．(把班级分成五个小组，每组六个学生。)此处指国营经济部门，所以应选B)。
