Each of the following is a technique used by astronomers to increase the amount of detail that can be seen or photographed through telescopes except one. Which is the exception?
A) antireflective coatings, where the mirror is coated with a substance, such as fluorite, to reduce the amount of reflected light
B) increased size, where mirrors are made far larger than was possible before, e. g., 8 to 10 m in diameter and larger
C) adaptive optics, where the tilt and shape of mirrors in the telescope are changed many times per second to compensate for atmospheric turbulence
D) multiple-mirror telescopes, where several mirrors are mounted together in a single telescope to simulate the performance of a single, very large mirror
