According to a different source, these are the options that come with this question:
-selection by electoral college
-direct popular election
-selection by Congress
-selection by state legislatures
The type of presidential selection that would make the most powerful executive would be direct popular election. This is because, in a democracy, the power of the state is considered to be found in the hands of the citizens. Therefore, the people are the only ones who can give this power up to the government. An executive that is elected by direct popular election would be one that has the support of the people, and thus the most power to rule.
