Look at the diagram and read the excerpt from Chapter Four of Windows to the Universe: Revolutions in Astronomy.The Optical Telescope Element (OTE): This is the "eye” of JWST that gathers light. It includes 18 hexagonal mirrors made of beryllium, chosen because it is lightweight and stable in extreme cold. The mirrors are coated in a thin layer of gold, which enhances the telescope's ability to collect infrared light. Despite the large surface area of the mirrors, the amount of gold used is minimal—if compressed, it would be about the size of a baseball.Which conclusion can best be drawn about the JWST's primary mirror compared to Hubble's?

Question illustration
Answer
A
JWST's mirror is smaller than Hubble's but more efficient due to its gold coating.
B
JWST's hexagonal mirrors were chosen primarily to make the telescope more visually appealing than Hubble's.
C
Hubble's mirror is better suited for infrared observations because it is a single, solid piece.
D
JWST's mirror was designed to collect more light than Hubble's, allowing it to see fainter and more distant objects.
