Lenses used in outer space video recording devices obviously require superior optical, thermal and barometric characteristics. In 2011, researchers at NASA synthesized a polymer, X21F702089 (Optical density = 0.02, Spectral absorption = 0.012) which is currently being used in all the recording equipment in their Curiosity space shuttle. Although the polymer performs flawlessly on Earth and in space (its optical density and spectral absorption remain constant), recent images of Mars captured by Curiosity suggest that, on Mars, X21F702Q89 has not been functioning the way it was supposed to This led to a battery of tests being conducted on X21F702089 in simulated Mars-like conditions. The research team for these experiments is led by Dr. Sy Fields, a nobel-prize winning Materials Science engineer. The tests continued until the polymer reached its maximum optical density. This is a portion of a graph (submitted by Dr. Fields' team) showing the variation of optical density and spectral density of X21F702089 with time spent in a Mars-like environment.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided in the graph
A. When the optical density of X21F702089 becomes 0.1, its spectral distribution is at approximately
B. When X21F702089 attains maximum optical density, its spectral distribution since its entry into Mars-like environment.
