The correct answer is A, as the Cumberland Road was significant because it was the first road constructed using federal funds.

The National Road (also known as Cumberland Road) was the first major managed road in the United States built by the federal government. Carried out between 1811 and 1837, the 1,000-kilometer route connected the Potomac and the Ohio River and was one of the western routes for thousands of settlers. When it was rebuilt in the 1830s, it became the second macadam-covered highway in the United States, using the process invented by the Scottish John Loudon McAdam.
