Choose the correct option out of the following choices.

Assertion: Polymers are formed by the repeating structural units.
Reason: The chemical process by which simple molecules or monomers are transformed into a polymer is known as polymerisation.

Assertion and Reason both are correct statement and the reason is the correct explanation for the assertion.

The correct answer is option 2. Assertion and Reason both are correct statement and the reason is the correct explanation for the assertion.

Assertion: Polymers are formed by the repeating structural units.

This statement is correct. Polymers are large molecules composed of repeating structural units known as monomers. These monomers are linked together through chemical bonds to form long chains or networks, resulting in the characteristic properties of polymers.

Reason: The chemical process by which simple molecules or monomers are transformed into a polymer is known as polymerisation.

This statement is also correct. Polymerization is indeed the chemical process through which monomers undergo a series of reactions to form polymer chains or networks. During polymerization, monomers are covalently bonded together, leading to the formation of polymers with unique physical and chemical properties.

Explanation: The reason provided correctly explains why the assertion is true. Polymers are indeed formed through polymerization, which involves the repetitive bonding of monomers to create large molecular chains or networks. Therefore, the assertion that polymers are formed by repeating structural units is true, and the reason clarifies the process by which this occurs.
