A. on both side; a number
B. on each sides; a number
C. on both sides; the number
D. on every side; the number

A. on both side; a number B. on each sides; a number (答案→)C. on both sides; the number D. on every side; the number解析：本题考查的both，表示两者都的意思，所以后接可数名词复数形式，因此将A排除，而each 与every表示每一个，后接可数名词单数形式，所以将B排除，而every表示的是三者或三者以上中的每一个，而路只有两边，故不能用every，故选答案为C，同时the number of sth后接可数名词复数形式，但作为主语时，相当于三单形式，也符合题意。
