The major employer of labour in developing countries is the

Step 1: Analyze the question The question asks which sector employs the largest share of the workforce in developing countries like Nigeria, Ghana, and others in West Africa.

Step 2: Explain the concept Economic activities are grouped into three sectors:

• Primary sector: extracting natural resources, including agriculture, fishing, forestry, and mining.
• Secondary sector: manufacturing and construction, which turn raw materials into finished goods.
• Tertiary sector: services such as banking, transport, trade, and education.

The industrial sector (option D) is mostly the same as the secondary sector, with mining sometimes included.

Step 3: Apply it to developing countries Developing economies usually have little industrialization and low technology. Most people therefore work in agriculture, mainly subsistence and small-scale farming. In Nigeria, for example, a large share of the population earns a living from farming, fishing, and related activities. Agriculture belongs to the primary sector.

Step 4: Eliminate the wrong options

• A. Tertiary: it is growing, but it is not the largest employer in most developing countries.
• B. Secondary: manufacturing is still small and underdeveloped.
• D. Industrial: this is similar to the secondary sector, with the same limitation.
• C. Primary: correct, since agriculture employs the largest share of the labour force.

Tip: Remember the pattern "Primary → Poor countries, Tertiary → Top (rich) countries." As a country develops, labour moves from farming (primary) to industry (secondary) and then to services (tertiary). If a question asks about a developing country, think of agriculture first.
