Step 1: Analyzing the Indian labor landscape.
In recent decades, India has seen a shift toward "Casualisation of the workforce." This means more workers are hired on a temporary, daily-wage basis rather than having long-term contracts.
Step 2: Evaluating the options.
- (A) and (D) are incorrect because the share of regular, formal, and salaried jobs has not grown as fast as the informal sector.
- (C) While self-employment remains high, the most critical "evolving trend" or shift discussed in economic literature is the move from regular work to casual work.
- (B) Correct. The rise in casual labor highlights issues of job insecurity and the lack of social security benefits (like pensions or insurance) for the masses.
Step 3: Conclusion.
The shift toward casual employment is a defining and problematic characteristic of the modern Indian labor market.
Final Answer: Increase in the proportion of casually employed individuals.
