The correct answer is 251.
This can be calculated by finding the proportion of students in the sample who prefer animated movies and then applying that proportion to the total number of students in the school.
48 (number of students who prefer animated movies in the sample) / 120 (total number of students in the sample) = 0.4 (proportion of students who prefer animated movies in the sample)
0.4 x 628 (total number of students in the school) = 251
Therefore, approximately 251 students in the school prefer animated movies.
