Answer:
The correct answer is A. In a presidential republic, the power of the president is kept in balance by power given to a legislative body.
Step-by-step explanation:
Presidentialism is a form of government in which, once a Republic is constituted, the Constitution establishes a division of powers between the Executive branch, the Legislative branch, the Judicial branch, and in which the Head of State, in addition of holding the formal representation of the country, is also an active part of the executive branch, as Head of Government, thus exercising a double function, and being elected directly by the voters and not by the Congress or Parliament.
The president is the organ that holds the executive power, while the legislative power is usually concentrated by the Congress, without prejudice to the powers that the president possesses in legislative matters.
