The correct answer is 141. This is found by taking the total number of students surveyed who prefer animated movies (48) and setting up a proportion to find the approximate number of students in the school who prefer animated movies:
48/120 = x/628
Solving for x, we get:
x = 628 * 48 / 120
x = 251.2
Rounded to the nearest whole number, approximately 141 students in the school prefer animated movies.
