【正确答案】 C

【答案解析】此题属于词语搭配题。Be liable to do/sth．意为“易于……的，有……倾向的，有义务的”，例如：(1)We are all liable to make mistakes．(2) People who walk on the grass are liable to a fine of ＄5．故选项[C]to 符合题意。选项[A] for 与liable 连用，be liable for sth．意为“有义务的”，例如：If we lose the case we may be liable for (have to pay) the costs of the whole trial．选项[B] of 和选项[D] with 均不能与liable 连用。
