C
"He discovered that all lenses suffer from something called chromatic aberration…. Newton realized this problem could be avoided by using mirrors instead of lenses."
D
"While Newton's reflecting telescope worked well, making the mirrors was still tricky and costly. As a result, his design didn't become widespread right away."
Explanation
The claim says advances in lens crafting and mirrors helped solve problems and improve telescopes. Choice C explains that lenses suffer from chromatic aberration and that Newton used mirrors to avoid this problem, directly supporting the claim. Choice D mentions difficulties making mirrors but does not explain how mirrors addressed a challenge.
