问题 Rules banning cancer-causing substances from food apply to new food additives and not to natural constituents of food because their use as additives is entirely avoidable.

选项 A、their use as additives is
B、as additives, their use is
C、the use of such additives is
D、the use of such additives are
E、the use of them as additives is

答案C

解析 A、B中their use的表达不仅句意不清,且不符合表达习惯;只有用the use of sth.表明“某物的使用(使用某物)”才符合习惯用法。D中主谓不一致;E中表达不够简洁,同时as addictive还会产生歧义。即它们本来是另一种物质,而在这里是充当添加剂,改变了句意。C正确,句中的such是对前面出现的new food addictive的强调。
