Corn seeds were germinated in a dark room. Not one of the seedlings was green.
When placed in the light, 75 percent of these seedlings turned green.
Which conclusion about chlorophyll production in corn plants can most reasonably be drawn from this information?

A) Light is the only factor that controls the production of chlorophyll.
B) Darkness is the only factor that prevents the production of chlorophyll.
C) Light and some other factor are necessary for chlorophyll production.
D) Light and vitamins are necessary for chlorophyll production.

We can conclude that the key element contributing to the development of chlorophyll in seeds or plants is light.  Adding on that, we should also understand that there are other components which also serve a part in the development of chlorophyll and do impact the result of the plants in the experiment.

What do you think is an appropriate choice for this conclusion?
