IMO all the options look nonsensical.Please quote the source of this Question.
"an advance" shall be "an achievement".IMO : A
Although I am not very sure about this answer choice.In Order to maintain parallelism the trailing part of the sentence shall use simple past,"an advancement that led".We need the help of some other enlightened soul
