Select the correct option based on statements below:

Assertion (A): Polyamides are best used as fibers because of their high tensile strength.
Reason (R): Strong intermolecular forces (like hydrogen bonding within polyamides) lead to close packing of chains and increase the crystalline character.
 
1. Both (A) and (R) are true but (R) is not the correct explanation of (A).
2. Both (A) and (R) are true and (R) is the correct explanation of (A).
3. (A) is true but (R) is false.
