Bcoz answer depends on how many other proportions are there in the household.

Let the proportion of expense on food to the total expense be x:y
The expense on food increases by 20%, making the expense on food 1.2x
Since this proportion has to remain constant, the total expense must become 1.2y(a 20% increase) (Option C)
