Options are not provded in the question. The complete question is:
All of the following substances are derived from petroleum EXCEPT
A) asphalt
B) DDT
C) cellulose
D) polystyrene
E) nylon
Answer: C) cellulose
Explanation:
Cellulose is defined as an organic compound made up of many hundred to several thousands of β linked D-glucose units arranged in a linear chain. Cellulose is a significant structural part of green plant's primary cell wall, many types of oomycetes and algae.
Human beings can not digest cellulose but as a source of fibre, it is essential in the diet. Cellulose is used for storing clothes and paper.
Hence, cellulose is not a derivative of petroleum.
