Typically, synthetic leather is petroleum based, but materials scientists searching for an ecologically sustainable alternative have used various bacteria that secrete linear chains of glucose, forming a dense mesh of cellulose called a pellicle, which is leatherlike except in color. The standard process for dyeing leather generates substantial wastewater and other undesirable byproducts, so adopting such a regimen would run counter to the ecological promise of the pellicle approach. To address this, Kenneth T. Walker and colleagues worked to modify Komagataeibacter rhaeticus bacteria to produce a pellicle with embedded pigmentation cells, thereby allowing the pellicle to "dye" itself from the inside.
Which choice best describes the function of the underlined portion in the text as a whole?
To illustrate how the researchers adapted the pellicle approach to overcome a potential impediment to their main goal as presented in the text
A
To concede that the researchers' main goal as described in the text will be challenging to achieve due to the standard coloring approach being impractical for use on a pellicle
B
To indicate the characteristic of conventional synthetic leathers that makes those leathers poorly suited to achieve the researchers' main goal as presented in the text
C
To describe a consideration that led the researchers to employ an alternative approach to coloring a pellicle that allowed them to achieve their main goal as presented in the text
D
