Option B

Explanation:

During the end of the 1800, a large number of people from all parts of the world decided to leave their home land and shift to the United States which had adverse effects on this country.

This led to the deficiency and reduction in the availability of land and jobs available and also led to the failure of crops. There also came a situation of famine in that country.

the correct answer is modern american cars are not available due to trade restrictions.

trade between cuba and the united states have serious restrictions. the u.s. imposed an economic embargo on cuba, that among other things means that modern american cars are not available due to trade restrictions.

in response to some governmental actions of the authorities from cuba, president john f. kennedy proclaimed an embargo on trade between both countries in february 1962. the trade embargo remains active until this day and was implemented directly by the departments of commerce and the department of treasury.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
