Recall that Tommy Twit's mother measures the departure of any bundle from her favorite bundle for Tommy by the sum of the absolute values of the differences. Her favorite bundle for Tommy is (2, 7), that is, 2 cookies and 7 glasses of milk. Tommy's mother's indifference curve that passes through the point (c, m) = (5, 4) also passes through

To create an indifference curve that passes through (c,m) = (5,4), we need to find bundles that have the same level of utility as (2,7) according to Tommy's mother's measurement. We can do this by finding bundles that have the same absolute difference in the number of cookies and glasses of milk as (2,7) and adding or subtracting those absolute differences to (c,m) = (5,4).

Using this method, we can see that the bundles in choice B all have the same departure from (2,7) as (5,4).

For example, for the bundle (2,1), the absolute difference in the number of cookies is 0 and the absolute difference in the number of glasses of milk is 6. When we add those absolute differences to (c,m) = (5,4), we get the bundle (5,10). Similarly, the other bundles in choice B have the same departure from (2,7) as (5,4), and therefore all lie on the same indifference curve.

On the other hand, none of the other choices have bundles that satisfy this criteria. Choice A has bundles with absolute differences that do not match up with (5,4), choice C has only one bundle and it does not match up with (5,4), and choice D has the same bundle as Tommy's mother's favorite, which would not create an indifference curve that passes through (5,4).
