What is the main purpose of the executive branch?

The main purpose of the executive branch is to enforce laws. The executive branch is responsible for implementing and administering public policy as established by the legislative branch. This includes executing federal laws, conducting diplomacy, and overseeing the various departments and agencies that enforce regulations and services. The President, as the head of the executive branch, has the authority to ensure that laws passed by Congress are carried out effectively and can influence, through executive orders and other actions, how laws are applied in practice.

In the context of the other options, making laws is the primary function of the legislative branch, which is tasked with drafting and voting on legislation. Interpreting laws is the role of the judicial branch, where courts analyze legislation and resolve disputes regarding its meaning. Amending laws can also involve both the legislative branch and processes for constitutional amendments, which require significant consensus and are not the domain of the executive branch.
