a. the u.s. acquired florida from spain.
b. the boundary between texas and mexico was defined.
c. the u.s. acquired alaska from russia.
d. the boundary between the maine and canada was defined.

Explanation:

The Webster - Ashburton Treaty of 1842 was mainly about resolving the border dispute between the United States (specifically Maine) and Canada (then part of British North America). Option A is about the acquisition of Florida (which was via the Adams - Onís Treaty), Option B is about the Texas - Mexico border (related to later treaties), and Option C is about the Alaska purchase (which was in 1867). So the correct result of the Webster - Ashburton Treaty was defining the boundary between Maine and Canada.

Answer:

D. The boundary between the Maine and Canada was defined.
