To determine the minimum age required for citizens to vote for President in the United States, we can refer to the relevant constitutional provisions.

In the U.S., the Constitution states that the minimum voting age for federal elections, including presidential elections, is 18 years. This was established by the 26th Amendment, which was ratified in 1971. The amendment was passed to ensure that younger citizens, particularly those who were being drafted into the military during the Vietnam War, had the right to vote.

Answer to the Question:

Citizens must be 18 years old to vote for President. Hence, the correct option is 18 years.
