Answer: D. calcium chloride

Calcium chloride molecules can be ruled out as the mystery molecule

Explanation:

Artificial membranes are also called as the synthetic membranes. It is created synthetically for the special separation purpose in the laboratory. 

It is used to separate large molecules like solid particles and big biological molecules like protein, DNA. 

They are produced from organic materials. Calcium chloride contains the chloride ion and calcium ion, as the chloride ion easily passes the artificial membrane so we can term calcium chloride as the mystery membrane that passes the artificial membrane easily.
