Every polymer is made up of repeated units of some monomer. Identification of the monomer is key to this problem.

Complete step by step answer:
-Cellulose fibres are generally obtained from the bark, wood or leaves of plants, or are at times derived from some other form of plant-like material. Chemically speaking, it can be obtained from ethers or esters of cellulose. Cellulose is also one of the polymers found in nature. This polymer is made out of repeated glucose monomer units.
-Polyester too is similarly a polymeric fabric which is used widely. It is obtained from the following monomers: terephthalic acid and ethane-1,2-diol. Hence, polyester is not obtained from cellulose.
-While preparing nylon, adipic acid and hexamethylenediamine are reacted to together. This results in the formation of nylon-6,6 and water. Hence, nylon is not produced from cellulose.
-In the case of rayon, first we need to prepare a soluble polymer known as viscose. This viscose can be prepared by reacting ammonia with copper sulphate, acid and cellulose. Once this soluble polymer is formed, it is converted to rayon.
Hence, rayon is obtained from cellulose.

Hence, Option D is the correct option.

A cellulose structure is formed by repeating glucose molecules, which are attached to each other from their end to end. It is similar to complex carbohydrates like glycogen. It is a straight chain polymer and its molecule has a long rod-like shape.
