The number of electoral votes for a president is equal to a. three-fifths of the total population of residents. b. three-fifths of the total population of registered voters. c. the number of members in state legislature. d. the number of representatives and senators from the state

The correct answer is D. Each state has a number of voters equal to the number of its senators (always two per state) and representatives in the Congress of the United States. In addition, under the Twenty-Third Amendment, the District of Columbia receives voters as if it were a state, but never more than the number of votes of the "least populated" state. The US territories are not represented in the Electoral College.
