Choice C is the best answer. In lines 85-86("Will...scale") the author asks, "Will companies be able to boost their products by manipulating online ratings on a massive scale?" In the context of selling products by manipulating user reviews, "boost" most nearly means promote.
Choices A, B, and D are incorrect because in the context of selling products by manipulating user reviews, the word "boost" refers to promoting the products, not making them larger or bigger (choice A), faster (choice B), or safe (choice D).
