The recent surge in the number of airplane flights has clogged the nation's air-traffic control system,"to lead to a 55 percent increase in delay at airports and prompt"fears among some officals that safety is being compromised.

C.to lead to a 55 percent increase in delay at airports and prompt
E.leading to a 55 percent increase in delays at airports and prompting

答案是E。OG的解释是leading和promoting是平行结构，且这两个词表the surge in flights的效果。我想问，C选项里to lead and prompt可以看做是在to之后的平行结构，而且这个不定式可以看做the surge in flights的定语，表目的啊，这样我觉得C选项也对，请NN帮我解释一下~顺便问一下，不定式可以做定语来表目的吗？
