The correct matching is Agro-based with Vegetable oil, Forest-based with Lac, Chemical-based with Salts, and Product-based with Soaps — option (C).

This question tests your understanding of how industries are classified based on the raw materials they use. The four categories given — Agro-based, Forest-based, Chemical-based, and Product-based — represent different sources of inputs, and you need to pair each with the correct example from Column II.

Let's take each industry type one by one.

Agro-based industries depend on agricultural produce as their raw material. Vegetable oil is extracted from oilseeds like mustard, groundnut, or sunflower — all farm products. So vegetable oil fits here. Lac is a resinous secretion from insects that live on trees — that's forest-based, not agro-based. So Agro-based must pair with Vegetable oil — that is 1-(iv).

Forest-based industries use raw materials from forests. Lac is a classic example — it is a natural resin obtained from the lac insect, which thrives on forest trees. So Forest-based pairs with Lac — 2-(iii).

Chemical-based industries use natural chemical minerals directly as their raw material. Common salt is exactly this kind of raw material — it is mined or obtained by evaporating seawater, and used directly (without being a manufactured product of some other industry) to make chemicals such as soda ash and caustic soda. So Chemical-based pairs with Salts — 3-(ii).

Product-based industries use the products of other industries — i.e., already processed/manufactured goods — as their own raw material, rather than a raw natural material. Soap is made by reacting vegetable oil (a product of the agro-based industry) with an alkali (a product of the chemical industry); its raw materials are themselves finished products of other industries, not raw natural inputs. So Product-based pairs with Soaps — 4-(i). …
