The correct order is:
D. Succession
A. Executive Order
B. Electoral College
C. Winner takes all
The order of succession is established by the Presidential Succession Act of 1947 and outlines who would become President if the President dies, resigns, or is removed from office. The Executive Order can be used by the President to establish policies and procedures within the executive branch. The Electoral College is the process by which the President is elected, and the winner takes all refers to the fact that the candidate who wins the majority of votes in a state receives all of that state's electoral votes.
