Choice B is the best answer because it presents a statement about Dorian that is directly supported by the text. The narrator of the text says that when Dorian sees his portrait, “his cheeks flushed for a moment with pleasure” and “a look of joy came into his eyes.” The narrator goes on to say that Dorian looked at the portrait “in wonder” and presents him as being so entranced by the portrait that he doesn’t notice what Hallward is saying to him. These details support the description of Dorian as being delighted by what he sees in the portrait. 
Choice A is incorrect because Dorian isn’t depicted as interested in Hallward’s opinion of the portrait; rather, he is so enraptured by the painting that he’s hardly even aware of Hallward. Choice C is incorrect because the portrait of Dorian is the only painting mentioned in the text. Although Dorian is depicted as being delighted with this particular portrait, there’s no evidence in the text that he likes portraits better than other kinds of paintings. Choice D is incorrect because nothing in the text suggests that Dorian is uncertain about Hallward’s talent. Instead, the text is focused on Dorian’s delight with the portrait.
