Which of the following statements about light industries is correct?
- (a)They process heavy ores and minerals.
- (b)They produce large-scale industrial machinery.
- (c)They require bulky and heavy raw materials.
- (d)Use light materials to make consumer goods
Answer
Why
Correct — D. NCERT's Class X geography classifies industries by the bulk and weight of raw material and finished goods.
Light industries "use light raw materials and produce light goods", its example being electrical goods. Fans, which NCERT also lists as consumer goods, are one such product.
That is the keyed statement → option (d).
Why the others are wrong
- (a)They process heavy ores and minerals. — Processing heavy ores and minerals is heavy industry. Iron and steel, NCERT's heavy-industry example, starts from iron ore, coking coal and limestone.
- (b)They produce large-scale industrial machinery. — Large-scale industrial machinery is a heavy-industry product: bulky goods made to equip other industries, not light goods for consumers.
- (c)They require bulky and heavy raw materials. — Bulky, heavy raw materials define heavy industry under NCERT's bulk-and-weight classification. Light industries are the opposite: light inputs and light outputs.
Concept
NCERT classifies industries in several ways: by source of raw material (agro-based, mineral-based), by main role (basic or key, and consumer), by capital investment, by ownership, and by bulk and weight.
Under bulk and weight, heavy industries such as iron and steel handle heavy, bulky inputs and outputs, and light industries use light raw materials to make light goods.
The schemes overlap: fans are light electrical goods and also appear in NCERT's consumer-industry list.
The keyed option drops the 'They' and the full stop that the other three carry. The wording is untidy, but the statement is the correct one.
Key facts
- NCERT (Class X, Manufacturing Industries) divides industries into heavy and light by the bulk and weight of raw material and finished goods.
- Light industries use light raw materials and produce light goods, NCERT's example being electrical goods.
- Iron and steel is NCERT's example of a heavy industry.
- Consumer industries make goods for direct use, such as sugar, toothpaste, paper, sewing machines and fans.

Common traps
- Rejecting the keyed statement because of its untidy wording: judge the content, not the punctuation.
- Confusing 'light' with 'small-scale': the heavy/light split is by the weight of materials and goods, while small-scale is defined by capital investment.
Here a classification is tested by describing one class. Heavy industry is asked through iron and steel at 12 Sep 2025, 16:00, GA Q.23, and the consumer goods industry at 14 Sep 2025, 09:00, GA Q.21 (keyed toothpaste).
