Engel's law says that proportion of income spent on food declines, although the expenditure may increase.
M= 1000, proportion on food = say 40% , then 400 is spent on food
M= 2000, proportion on food = 30% , then 600 is spent on food.
So its not necessary that expenditure on food declines.
The proportion declines.

And option b says 'at least 270 students'.
So i guess its e
