What is elasticity in polymers generally related to?

amount of hydrogen bonding between different subunits
number of subunits in the polymer chain
its greater tensile strength
the synthetic composure

Its greater tensile strength.

Explanation:

According to the law of elasticity, elasticity is the property or nature of any material, which is the reason to return itself to its original shape when it is de-shaped or deformed for any reason. As an example, we can say about spring. Spring comes to its original shape when it is stretched and then released. So the property that brings the spring back to its original form is called elasticity.

On the other hand, tensile strength is the greatest stress that a material can withstand before it breaks since polymers are also elastic, so the higher tensile strength means more excellent elasticity. A tensile tester is used to measure the tensile strength of any material.
