Question

Assertion (A): Traditional raw materials are being replaced by petrochemical products.

Reason (R): The raw materials of the petrochemical industry are derived from petroleum.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

Petrochemical products are made from petroleum-derived feedstocks (e.g., naphtha, ethylene, benzene), so they can be mass‑produced cheaply. Because these petroleum-based materials are abundant and cost‑effective, they have replaced many traditional materials (wood, glass, metals, natural fibres) in many uses.
