B. Making wool
C. Making jewellery
D. Wholesale trade
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A, B and C only
Secondary activities add value to natural resources by turning raw materials into valuable products. They cover manufacturing, processing and construction.
(A) Iron and steel industry — Correct. It turns iron ore, a ferrous mineral, into steel. It is a mineral based industry.
(B) Making wool — Correct. Wool from animals is the raw material of the woollen textile industry, an animal based industry. Processing wool is manufacturing.
(C) Making jewellery — Correct. Jewellery industries use non-ferrous metallic minerals as raw material. Goldsmiths also make jewellery as a household industry.
(D) Wholesale trade — Incorrect. Trade is buying and selling of goods made elsewhere. It makes nothing new, so it is a tertiary activity.
Note: The given answer is as per the official NTA Answer Key. The book does not use the words ‘making wool’. It places wool for woollen textiles under the animal based industries, so making wool is read here as processing wool, a secondary activity.
NCERT (2026-27): “Secondary activities add value to natural resources by transforming raw materials into valuable products. … Secondary activities, therefore, are concerned with manufacturing, processing and construction (infrastructure) industries.” “(b) Mineral based Industries … These industries use minerals as a raw material. Some industries use ferrous metallic minerals which contain ferrous (iron), such as iron and steel industries but some use non-ferrous metallic minerals, such as aluminium, copper and jewellery industries.” “(e) Animal based Industries … Leather for leather industry and wool for woollen textiles are obtained from animals.” “Trade and commerce … Trade is essentially buying and selling of items produced elsewhere. All the services in retail and wholesale trading or commerce are specifically intended for profit.” |
