Industries are broadly classified into

Step 1: Analyze the question The question asks how industries are broadly classified. It is asking for the main categories, not examples of specific industries.

Step 2: Explain the concept In Geography (Economic Geography), industries are grouped by the kind of economic activity they carry out:

• Primary industries: extract or harvest raw materials directly from nature. Examples: farming, fishing, mining, lumbering, and crude oil extraction.
• Secondary industries: turn raw materials into finished or semi-finished goods. Examples: manufacturing, cocoa processing, furniture making, and textile production.
• Tertiary industries: provide services. Examples: banking, transport, teaching, trade, and healthcare.

(Some books add quaternary and quinary industries, but the three above are the basic broad classification.)

Step 3: Check each option

• A. primary, secondary and tertiary: These are the three broad categories. ✔
• B. mining, furniture making and cocoa processing: These are examples of specific industries, not a classification. Mining is primary, while the other two are secondary. ✘
• C. fishing, mining and food processing: These are also examples. Fishing and mining are primary, and food processing is secondary. ✘
• D. primary, secondary and manufacturing: Manufacturing is part of the secondary category, so it is not a separate class. ✘

Step 4: Answer The correct option is A. primary, secondary and tertiary.

Exam tip: Remember the order P-S-T, which follows the production chain: Produce raw materials → Shape them into goods → Transport and sell them or provide services. If the options list specific examples such as mining or fishing instead of category names, they are usually distractors for a "broad classification" question.
