What was the major obstacle for manifest destiny? the foreign wars
other country possessions
the frontier settlers
the president

The correct answer is B) Other country's possessions

Explanation:

By then 19th century, America was still a very small country compared to modern borders. However, many American politicians believed in a 'Manifest Destiny' in order to expand the country from coast to coast.

Small frontier settlements as far as California already existed and the idea was encompass all of the land between Canada in the north and Mexico in the South.

However, the major obstacle for this were the various North American possessions of other countries.

One example was of Louisiana, a part of land in North America owned by the French Empire. At the time, this was larger than the rest of the United States. Eventually the French agreed to sell it.

Spain was another major land holder in North America including the large possession of Florida.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
