CorrectNot quiteAnswer C

Correct answer: C

Science's slice is 90°, which is $90 \div 360$ = ¼ of the circle.
Students: $\frac{90}{360} \times 1{,}800 = 450$ .

Worth noting

90 is the angle of the slice, not the number of students. 1,620 treats 90° as if it were 90%. 360 is the number of Commerce students.

Concept: Converting a central angle into a count
