Assertion: The participation rate of workers in secondary and tertiary sector has registered an increase during the last few decades in India.

Reasoning: There is a shift of dependence of workers from farm based occupations to non-farm based ones, indicating a sectoral shift in the economy of the country.

Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

The correct answer is Option 1: Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

Assertion: The participation rate of workers in secondary and tertiary sector has registered an increase during the last few decades in India. This statement is correct because over time, more workers have moved towards industrial and service sector occupations.

Reasoning: There is a shift of dependence of workers from farm based occupations to non-farm based ones, indicating a sectoral shift in the economy of the country. This is also correct. The rising participation in these sectors is a direct result of workers moving away from traditional agriculture. This movement is known as a sectoral shift. As an economy develops, the dependence on the primary sector typically decreases as opportunities in industrial and service-oriented fields expand.

Why R is the Correct Explanation for A

The Reason correctly explains the Assertion because the movement of workers away from agriculture towards industrial and service sector occupations leads to increased participation in secondary and tertiary sectors. This reflects the structural or sectoral shift taking place in the Indian economy.

NCERT: "It is important to note that the proportion of workers in agricultural sector in India has shown a decline over the last few decades (58.2% in 2001 to 54.6% in 2011). Consequently, the participation rate in secondary and tertiary sector has registered an increase. This indicates a shift of dependence of workers from farm based occupations to non-farm based ones, indicating a sectoral shift in the economy of the country."
