This question asks to classify manufacturing within the sectors of economic activity. Understanding the definitions of primary, secondary, tertiary, and quaternary sectors is key to answering this question.
Correct Option: D) Secondary sector — Manufacturing involves the transformation of raw materials into finished goods, which is the defining characteristic of the secondary sector of economic activity.
The question asks for the classification of industries based on the source of raw materials. We need to evaluate each option to see which one aligns with this specific criterion.
D) Agro-based and Mineral-based is the correct classification of industries based on the source of raw materials. Agro-based industries derive their raw materials from agriculture, while mineral-based industries use minerals as their primary raw materials.
To identify an agro-based industry, we need to understand its definition: an industry that uses agricultural products as its raw materials. We will evaluate each option based on this definition.
Correct Option: A) Cotton textile, jute, silk, rubber, sugar, tea and coffee industries are all examples of agro-based industries because they directly process agricultural produce.
The question asks to classify industries like iron and steel, cement, aluminium, machine tools, and petrochemicals based on their raw material source. We need to identify the primary raw materials used in these industries and match them with the given classification types.
Correct Option: A) Mineral-based industries. The industries mentioned (iron and steel, cement, aluminium, machine tools, and petrochemicals) all use minerals or mineral-derived products as their fundamental raw materials. Iron ore, limestone, bauxite, petroleum, and natural gas are all examples of minerals or mineral resources.
The question asks for the definition of 'Basic or Key industries'. We need to identify the option that best describes industries fundamental to the economy by providing raw materials or essential inputs for other sectors.
C) Supply their products as raw materials for manufacturing other goods (e.g., iron & steel, copper smelting, aluminium smelting)
This option accurately defines 'Basic or Key industries' as those that provide essential inputs or raw materials for other industries. These foundational industries are crucial for the development and functioning of the entire industrial economy.
The question asks to identify a correct example of a 'Consumer industry'. A consumer industry produces goods directly used by the end consumers. We need to evaluate each option based on whether the listed items are final products for direct consumption or intermediate goods/raw materials.
Correct Option: D) Sugar, toothpaste, paper, sewing machines and fans. These items are directly consumed or used by the end-users, fitting the definition of products from a consumer industry.
