­Overused phrases, known as clichés, are rightly criticized because

The argument posits that politicians would be more successful at communicating their policies and getting elected if they avoid using clichés in their speeches. To undermine this reasoning, we need to find an option that suggests the use of clichés is not necessarily detrimental to a politician's success in communicating policies and getting elected.

Let's evaluate each option:

(A) This option suggests that voters prioritize the policies of the candidates' parties over the candidates' own policies. This doesn't directly address whether the use of clichés affects a politician's success in communicating policies.

(B) This option implies that unclear communication of policies can aid candidates in getting elected. However, it doesn't specifically address the use of clichés.

(C) This option suggests that candidates often have to repeat the same speech to different audiences. While this may imply that the use of clichés could become apparent and potentially less effective, it doesn't directly undermine the argument's reasoning.

(D) This option reinforces the importance of voters' understanding of the candidate's policies, which aligns with the argument's premise. It does not undermine the reasoning.

(E) This option emphasizes that most candidates are genuinely interested in being elected based on their favored policies. While this is relevant to the motivation of candidates, it doesn't address whether the use of clichés affects their success in communicating policies.

Among the options, (B) seems to best undermine the argument's reasoning by suggesting that unclear communication, which might include the use of clichés, could actually aid a candidate's efforts to get elected. Therefore, (B) would be the most appropriate choice.­
