Which of the following is a power of the president?

Vetoing legislation is a significant power of the president within the United States government. The president can reject bills passed by Congress, preventing them from becoming law. This authority serves as a check on the legislative branch, ensuring that the president has a say in the laws that govern the nation. The veto power is vital for maintaining a balance of power among the branches of government and for allowing the president to influence legislation in line with their policy priorities and the interests of the nation.

While other options may seem like presidential powers, they do not accurately reflect the role of the president. For example, making laws directly is primarily the responsibility of Congress, and while the president can propose legislation, the actual lawmaking process requires legislative approval. Declaring war without Congress is not permissible due to the War Powers Resolution, which mandates that Congress must authorize military engagement. Approving appointments of judges is also a presidential power, but it is subject to Senate confirmation, making it a collaborative process rather than an executive action.
