Question

Quizplus · Accepted Answer

The graph in option B shows an indifference curve with tea and coffee at different quantities but the same level of caffeine intake. This is because coffee has twice as much caffeine as tea, so Caroline would need to consume half as much coffee to get the same amount of caffeine as tea. Option A has a curve showing a negative relationship between the quantity of tea and coffee and the level of caffeine, which does not accurately reflect Caroline's preference. Option C has a curve showing a positive relationship between the quantity of tea and coffee and the level of caffeine, which also does not accurately reflect Caroline's preference. Option D does not show any indication of caffeine intake on the graph.
