Choice C is the best answer. The first sentence of the fifth paragraph states, "Not unexpectedly, the statistical strength of the findings made a huge difference in whether they were ever published." This statement is supported by the graph, which shows that more than 60 percent of social science studies that produced strong results were published, while only about 50 percent of studies with mixed results and about 20 percent of studies with null results were published.
Choices A, B, and D are incorrect because none of the cited lines contain information that is represented by the data in the graph. Instead, they recount scientists' explanations for why they didn't publish their null results (choices A and B) and highlight claims about the importance of Malhotra's study (choice D).
