To determine which sentence in the given options has the use of prepositional phrases that make it harder for readers to find the main point, we need to analyze each sentence's structure and identify any excessive or convoluted prepositional phrases.

A. "The senator chose to run on a platform that cut taxes for the wealthy." - This sentence does not contain any excessive prepositional phrases. The main point is clear: The senator has chosen a platform that involves cutting taxes for the wealthy.

B. "In what way is a political group considered 'grassroots' when it's overseen by a pair of wealthy businessmen?" - Though there is a prepositional phrase in the beginning ("In what way"), this question format does not hinder readers from understanding the main point. The main point of the sentence is questioning how a political group can be considered "grassroots" when it is overseen by wealthy businessmen.

C. "Under the circumstances in which the staff found themselves, they decided, in anticipation of layoffs, to go on strike." - This sentence contains multiple prepositional phrases. "Under the circumstances in which the staff found themselves" and "in anticipation of layoffs" are both prepositional phrases that complicate the sentence. These phrases create unnecessary complexity and make it harder for readers to identify the main point. Therefore, C is the sentence in question.

D. "The committee voted on several of the issues under consideration." - This sentence contains a prepositional phrase ("under consideration"), but it does not make it harder for readers to find the main point. The main point is clear: The committee voted on several issues.

So, the correct answer is C.
