选项 A、Supplying
B、Getting
C、Providing
D、Furnishing
答案 B
解析 本题空格所在句子是让步状语从句的复合句，空格部分和enough vitamins构成动名词的复合结构做主句的主语。空格处填入的动名词的逻辑主语也就是后面although引导的让步状语从句中的主语，即：the body。动名词所表示的动作必须是the body发出来的，又能接enough vitamins做宾语。选项中，supplying，providing和furnishing均表示“提供，供应”，动作的发出者不是“身体”。句子表达的含义是身体需要获取维生素的营养，而不是“提供”，因此只有Getting(获取，获得)符合。故选B。
