1.        Many writers of modern English have acquired careless habits that damage the clarity of their prose, but these habits can be broken if they are willing to take the necessary trouble.

(A) but these habits can be broken

(B) but these habits are breakable

(C) but they can break these habits

(D) which can be broken（C）

(E) except that can be broken

我怎么看到又选B又选C的,到底是哪个啊啊啊

C is the obvious choice.

B is not right b/c if the subject is switched to "this habits", then we don't know whom the "they" after "if" refers to.

i second with mbz.

BTW,breakable in b sounds awkward

C

b 主语不对
