Which of the following is an example of checks and balances? Select all that apply.

To determine which of the following is an example of checks and balances, we first need to understand what checks and balances mean.

Checks and balances is a system in government where one branch has the ability to limit the power of another branch to prevent any one branch from becoming too powerful. This system ensures that each branch of government can restrain the actions of the others, thus providing a balance of power.

Now, let's review the options and identify which ones demonstrate checks and balances:

a) The president appoints federal judges.
b) The Senate confirms or rejects nominations for federal judges.
c) The Supreme Court has the power to declare laws unconstitutional.
d) The House of Representatives writes and passes laws.

From the options given, options b) and c) are examples of checks and balances:
- Option b) - The Senate confirms or rejects nominations for federal judges: This demonstrates a check on the President's power to appoint judges. The Senate has the authority to approve or reject these nominations, thus providing a balance of power.
- Option c) - The Supreme Court has the power to declare laws unconstitutional: This demonstrates a check on the power of the legislative branch (Congress) because the Supreme Court has the authority to rule whether laws are in line with the Constitution. In doing so, the Supreme Court provides a check on the actions of Congress.

Therefore, options b) and c) are examples of checks and balances.
