Choice B is the best answer. The graph clearly shows that gift-givers believe that a "more valuable" gift will be more appreciated than a "less valuable gift." According to the graph, gift-givers believe the monetary value of a gift will determine whether that gift is well received or not.
Choice A is incorrect because the graph does not suggest that gift-givers are aware of gift-recipients' appreciation levels. Choices C and D are incorrect because neither the gift-givers' desire for the gifts they purchase nor the giftgivers' relationship with the gift-recipients is addressed in the graph.
