It is not uncommon for an executive agreement to be made
a- after a president is elected
b- before a president signs a treaty
c- after a treaty is made
d- before a treaty is made

The correct answer is D. A President often makes an executive agreement before a treaty is made. In this context, an executive agreement is best understood as a sort of "preliminary" treaty, and it can guide the eventual treaty that Congress adopts. An executive agreement, however, carries less authority than an actual treaty ratified by Congress.
