Since the each of the 12 songs is selected 4 times, the total number of song selections = 12*4 = 48.
Since each student makes 2 selections, we get:
Number of students = (total selections)/(selections per student) = 48/2 = 24.

The correct answer is D.

Since each of the 12 songs was selected 4 times, thus there were a total of 12 x 4 = 48 song selections. Since each student had 2 song selections, there must be 48/2 = 24 students.

Answer: D
