Explanation:

Parallel structure requires that similar elements in a sentence have the same grammatical form. In this case, the original sentence has a list of actions (improve traffic, help the environment, encourage employees to use alternative means). Option D maintains parallelism by using the same verb - phrase structure ("reward employees who take advantage of these offerings") as the other elements in the list.

Answer:
