The correct answer is bilateral (D).
<em>A bilateral system</em> means a government with two legislative houses.The federal government in the USA uses the bilateral system and so do all the states with the exception of Nebraska. The bicameral system in the U.S consists of: The House of Representatives and the Senate. Each house has different requirements to serve and each house has unique powers.

They ensure that no one person or department has an absolute control over decisions. Checks and balances create separation of powers. In the U. S. checks and balances are exercised through its three branches of government: the legislative, the executive and the judicial. Each branch has special abilities. The legislative branch makes the laws but the executive branch gives the veto power to the president to veto these laws if necessary. The judicial branch may deem certain laws unconstitutional thus making them void.
