To help combat the growing rate of microplastic pollution, a team of researchers developed a synthetic sponge that can soak up microplastic particles from liquid. The sponge, composed mainly of starch and gelatin, does this by trapping the tiny particles within its pores. Guoqing Wang, one of the researchers, says that the formula for the sponge can be adjusted to best suit the size of particle the sponge is intended to trap, making it versatile in its potential applications. Chemist Christian Adlhart, however, claims that this sponge would be difficult to mass-produce.
Which finding, if true, would most directly support Adlhart's claim?
Textiles are one of the largest sources of microplastic pollution in our oceans.
A
The sponge created by Wang and his team has a relatively light weight for its volume, making it potentially easy to ship to different locations.
B
The absorption capabilities of the sponge created by Wang and his team varied depending on the liquid solution used in the team's experiments.
C
The worldwide supply of starch and gelatin is in high demand from the food industry, so those substances would be difficult to source in significant quantities.
D
