Choice D is the best answer. The second paragraph states that "TESS allows scientists to order up Internet-based surveys." In the context of the service that the TESS program provides to scientists, "allows" most nearly means enables.
Choices A, B, and C are incorrect because in the context of the passage's discussion of TESS, "allows" most nearly means enables, not admits (choice A), tolerates (choice B), or grants (choice C).
