In its search for new technologies for solar energy that can produce lower-cost electricity, Smith-Diatom is developing a new way to make dye-sensitive solar cells, in which photons strike light-sensitive dyes. The process uses diatoms, which are unicellular algae that have silicon shells with a complex structure. First, the organic material is removed, and then the shells are coated with a titanium dioxide film that acts as a semiconductor. The diatoms' structure results in more photon activity and thus more efficient production of electricity than with current dye-sensitized solar cells, which in turn lowers the cost. Which of the following considerations would, if true, most strongly support the hypothesis that the plan, if implemented, will produce low-cost electricity from dye-sensitive solar cells?
A: Diatoms are an important link in oceanic food chains and help cycle carbon dioxide from the atmosphere.
B: Because diatoms occur naturally, no special engineering processes are needed to produce the basic dye-sensitive solar cell structures.
C: Dye-sensitive solar cells work somewhat more efficiently in lower light than previous solar cell technologies.
D: The production of dye-sensitive solar cells primarily uses materials that do not harm the environment.
