To find the percentage of students in 4-year programs who are 18 to 21 years old, we need to look at the column labeled "4-year programs" and the row labeled "18-21 years old". The entry in the table is 728.8, which represents 728,800 students. To find the percentage, we need to divide this number by the total number of students in 4-year programs, which is the sum of the entries in the "4-year programs" row: 728.8 / 1,064.7 = 0.684 or 68.4%. Therefore, the answer is D, about 68.4%.
