What options does the president have when presented with a bill?

When presented with a bill, the president's options clearly include the ability to sign it into law, veto it, or ignore it. Signing a bill into law indicates that the president approves of its content and wants it to take effect. A veto means the president disapproves of the bill, effectively stopping it from becoming law unless Congress overrides the veto. The option to ignore a bill is significant as well—if the president does not sign or veto the bill within ten days while Congress is in session, it automatically becomes law. Alternatively, if Congress adjourns during that ten-day window, the bill does not become law, a situation known as a pocket veto.

The other choices do not accurately reflect the president's power regarding legislation. While some terms used in the incorrect options like "reject" and "dismiss" might seem similar to vetoing, they don't capture the formal legislative processes appropriately, such as the mechanics of a veto or the concept of a pocket veto. Thus, the correct answer embodies the precise constitutional powers held by the president in the legislative process.
