The recent surge in the number of airplane flights has clogged the nations air-traffic control system, *to lead to 55 percent more delays at airports, and prompts* fears among some officials that safety is being compromised.

A) to lead to 55 percent more delays at airports,and prompts
B) leading to 55 percent more delay at airports and prompting
C)to lead to a 55 percent increase in delay at airports, and prompt
D)to lead to an 55 percent increase in delays at airports, and prompted
E)leading to a 55- percent increase in delays at airports, and prompting

IMO is E, leading and prompting are ||al and leading to is correct usage.

IMO E

percent more - X percent more than Y means X + Y percent
percent increase - X percent increase - Y + X% of Y

even i think its E...

my stab is on E
