OFFICIAL EXPLANATION
Medical innovations increase efficiency, low costs, and save lives
A. low costs
This answer choice is grammatically incorrect. The first and last items in the list at the end of the sentence are conjugated verbs (increase, save), but the middle item is a noun (costs).
Note that the word costs can serve as both a noun and a verb. We can tell that in this case it's a noun because of the adjective low that appears immediately before it.
What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign: A list of 3 items or more, separated by commas and and/or before the last item.
B. lead to far lower costs
Although this answer choice corrects the original Parallelism mistake and is grammatically correct, it is stylistically flawed. The wordy phrase lead to far lower costs creates redundancy.
C. to cost less
This answer choice repeats the original Parallelism mistake. The first and last items in the list at the end of the sentence are conjugated verbs (increase, save), but the middle item in this answer choice is an unconjugated verb (to cost).
Remember: A conjugated verb parallels only other conjugated verbs.
What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign: A list of 3 items or more, separated by commas and and/or before the last item.
D. lower costs
In the original sentence, the first and last items in the list are conjugated verbs (increase, save), but the middle item is a noun (costs). This answer choice corrects the mistake by using the verb lower.

A. low costs
Incorrect. We are looking at a list, which means that each thing in the list will have to make sense standing alone with 'Medical innovations...'. In this case "Medical innovations low costs" is grammatically wrong.
B. lead to far lower costs
Incorrect. Redundant.
C. to cost less
Incorrect. Parallelism issue.
D. lower costs
Correct. "Medical innovations lower costs" stands well by itself.
E. minimum costs
Incorrect. Parallelism issue.
