Final answer:
A state with 1,200,001 citizens would have 4 Electoral College electors, calculated by adding the two guaranteed senators to their two representatives based on population. Hence, the correct answer is option C.
Step-by-step explanation:
A state with 1,200,001 citizens would receive 4 Electors for President. This is determined by adding the number of U.S. Senators, which is always two, to the number of U.S. House Representatives. Since the apportionment of House seats is based on population, and it takes roughly 600,000 people to gain an additional House seat, a state with 1,200,001 citizens would have enough population for two Representatives. Therefore, with two Senators and two Representatives, the total number of Electors would be four.
