Answer 2

The strongest fibre is called Rayon.

Option: (a)

Explanation:  

• All of the above are synthetic fibres. Now if we compare the tensile strength of these compounds then Rayon is the most strong.  

• Rayon is used in the manufacture of hard and tensile ropes. Now Rayon is made from wood. The alkaline degradation of wood pulp is done.  

• Hence the cellulose which is present in wood is converted to a strong formulation.  

• Rayon can be made into different types. There is a high wet modulus type of rayon, which is stronger than the original rayon.
