Choice A is the best answer. In lines 65-67（"The...waves"）, the author notes that Tom Peacock and his team “were able to devise a mathematical model that describes the movement and formation of these waves.” In this context, the researchers devised, or created, a mathematical model. Choices B, C, and D are incorrect because in this context “devise” does not mean to solve, imagine, or begin.
