Explanation
Correct answer: A.
Choice A is the best answer because it most effectively uses data from the graph to complete the statement. The graph shows test results for two new battery recycling processes used with two types of lithium-ion batteries, type A and type B. According to the graph, recycling process 2 recovered the highest percentage of lithium in the tests: recovering about 75% from lithium-ion battery type B.
Why the other choices are wrong
Choice B
Choice B is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 10%. In fact, none of the tests recovered exactly 10% of lithium from a recycling process.
Choice C
Choice C is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 45%. In fact, none of the tests recovered exactly 45% of lithium from a recycling process.
Choice D
Choice D is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 20%. In fact, none of the tests recovered exactly 20% of lithium from a recycling process.
