The Correct answer is D.

Explanation

From the circle graph, 30% of the students surveyed chose Action and 14% chose Fiction as their favorite movie genre. Hence ?40 students is equal to 30%-14%=16% of the total number of students surveyed. Let ?N be the number of students surveyed; then the last statement can be written symbolically as 0.16N=40. Solving for N gives N=250. Therefore, the total number of students surveyed was 250.
