Critical Reasoning (CR) | Re: Manufacturers of writing paper need to add mineral filler to paper

Manufacturers of writing paper need to add mineral “filler” to paper pulp if the paper made from the pulp is to look white. Without such filler, paper products look grayish. To make writing paper that looks white from recycled paper requires more filler than is required to make such paper from other sources. Therefore, barring the more efficient use of fillers in paper manufacturing or the development of paper-whitening technologies that do not require mineral fillers, if writing paper made from recycled paper comes to replace other types of writing paper,paper manufacturers will have to use more filler than they now use.

Which one of the following is an assumption on which the argument depends?

(A) Certain kinds ofpaper cannot be manufactured from recycled paper. - WRONG. Irrelevant. 
(B) The fillers that are used to make paper white are harmful to theenvironment . - WRONG. Irrelevant.
(C) Grayish writing paper[color=#27ae60] will not be a universally acceptable alternative
