Answer:
option C is the answer
Step-by-step explanation:
From the question we are told that the bundle (10,10 ) gives the utility that is = 4
And also for Leonid more is better(i.e more bundle of food and transportation consumed the more his utility ) then we can infer that the utility for the bundle (20,20) would be greater than 4
And looking at the option the only value greater than 4 is 1000 hence option c is the answer
