Answer:
Option D, before a treaty is made, is the right answer.
Step-by-step explanation:
An agreement between the delegates of two or more countries that have not been approved by the government as agreements are ratified is known as an executive agreement. Such agreements are regarded as politically requisite to distinguish them from treaties that are bounded legally. An executive agreement is generally made before a treaty is made, accordingly, it may be understood as a "preliminary" treaty.
