b. puerto rico has its own currency.
c. puerto rican citizens do not vote for the president.
d. puerto ricans are free to move to any other place in the us.

Puerto Rico has its own currency.

Explanation:

Puerto Rico is an archipelago located in the Caribbean Sea and its territory is part of the United States of America. Citizens of Puerto Rico have American nationality and can move freely between the island and the mainland, having the freedom to live in any of the American states.

However, Puerto Rico is considered an associated free state, but it is not a federative state, so Portorican citizens do not vote to elect the president of the United States unless they reside on the continent. Thus, Puerto Ricans are represented in Congress by only one non-voting advisory commissar, but Washington has the prerogative of decision on matters of the Puerto Rican island, including with regard to monetary policy, since the American dollar is the official currency of Puerto Rico, which does not have its own currency.
