Answer:
The correct answer is e) the threat of the quadruple alliance to reestablish.
The Monroe Doctrine was issued by President James Monroe in 1823 in response to the threat of the Quadruple Alliance (Britain, France, Austria, and Prussia) to reestablish their colonies in the Americas.
The Doctrine asserted the United States' position that any attempt by a European power to colonize or interfere in the affairs of the Americas would be seen as an unfriendly act towards the US.
