Clothes obtained from cellulose are :

Question

Accepted Answer

Option 1, "Cotton and Rayon," is the correct answer because both cotton and rayon are derived from cellulose, which is a natural polymer found in the cell walls of plants.

1. **Cotton**: Cotton is a natural fiber that is directly obtained from the cotton plant. The primary component of cotton is cellulose, which makes up about 90% of the fiber. Cellulose is a carbohydrate polymer that provides structure to plant cells, and in the case of cotton, it is spun into threads to make fabric.

2. **Rayon**: Rayon is a semi-synthetic fiber made from regenerated cellulose. The process of making rayon involves dissolving cellulose from wood pulp or cotton linters and then regenerating it into fibers. Although it undergoes chemical processing, the base material for rayon is still cellulose, making it a cellulose-derived fabric.

Now, let's explain why the other options are incorrect:

- **Option 2: Rayon and Nylon**: While rayon is derived from cellulose, nylon is a completely synthetic fiber made from petrochemicals. Nylon is a polyamide, not related to cellulose, and is produced through a chemical process involving the polymerization of monomers like adipic acid and hexamethylenediamine.

- **Option 3: Nylon and Silk**: As mentioned, nylon is a synthetic fiber not derived from cellulose. Silk, on the other hand, is a natural protein fiber produced by silkworms. It is composed of proteins like fibroin and sericin, not cellulose. Therefore, neither nylon nor silk is obtained from cellulose.

- **Option 4: Silk and Cotton**: While cotton is indeed a cellulose-based fiber, silk is not. Silk is a protein-based fiber, as explained earlier. Therefore, this option is incorrect because only one of the two fibers listed (cotton) is derived from cellulose.

In conclusion, Option 1 is the correct answer because both cotton and rayon are obtained from cellulose, whereas the other options include fibers that are either synthetic or protein-based and not derived from cellulose.
