OPTION----B
The number of students is 48
Explanation:
Let the number of students = y
let the number of benches = x
from the first statement
y=4x−12 (three empty benches * 4 students)
from the second statement
y=3x+3
Substituting equation 2 into equation 1
3x+3=4x−12
rearranging
x=15
Substituting the value for x in equation 2
y=3⋅15+3=48
