Answer:
[tex]\boxed {\boxed {\sf B. \ The \ patriots \ were \ most \ familiar \ with \ the \ land \ and \ where \ they \ were \ fighting}}[/tex]
Explanation:
In the Revolutionary War, the British had an overwhelming amount of advantages over the Patriots.
The British had more money, more developed manufacturing, better trained soldiers, more equipment, and more.
The Patriots had little money, underdeveloped industries, volunteer armies, but they had the advantage of fighting on their home turf.
We can eliminate choice A (the Patriots, not British had volunteer armies), C (relying on slave labor-which was cheap- would not be a disadvantage) and D (the Patriots had almost no money).
Therefore, the best answer choice is B. The patriots were most familiar with the land and where they were fighting.
