To Whitney, the finding offers further evidence of plants' incredible versatility. Because they are unable to move when conditions are unfavorable, they must find other ways of adapting to the world around them. Often, they adapt chemically. The development of a purple photosynthetic chemical on early Earth is an example of this, as it was well suited to the kinds of light that were available at the time. Which of the following can be inferred from this paragraph?

A
Scientists believe that plants will be able to move in the next 100 years.
B
More plants have physical adaptations than chemical adaptations.
C
Plants are able to make changes to their chemical structures based on their environments.
D
Sunlight was seen as purple, not yellow, in the early years of Earth's history.
