The correct answer is option 'E', which means both disguised unemployment and seasonal unemployment are found in the agriculture sector of India. Let's understand each type of unemployment in detail:

1. Disguised Unemployment:
- Disguised unemployment refers to a situation where more people are employed in a particular activity than actually required.
- In the context of the agriculture sector in India, disguised unemployment occurs when there are too many workers engaged in agricultural activities, but their marginal productivity is zero or negligible.
- This means that even if some workers are removed from the sector, the overall productivity of the sector will not be affected.
- Disguised unemployment is more prevalent in labor-intensive sectors like agriculture, where there is a lack of alternative employment opportunities.

2. Seasonal Unemployment:
- Seasonal unemployment is a type of unemployment that occurs due to the seasonal nature of certain industries or occupations.
- In the case of the agriculture sector in India, seasonal unemployment is primarily observed in regions where farming activities depend on monsoon or specific seasons.
- During non-agricultural seasons or off-seasons, when there is no or limited farming work available, many agricultural workers become unemployed.
- These workers are temporarily unemployed during the off-season and often seek alternative sources of income or migrate to other areas in search of employment.

Combining the above two types, the agriculture sector in India experiences both disguised unemployment and seasonal unemployment. Disguised unemployment occurs when there are more workers engaged in agricultural activities than required, leading to low productivity. On the other hand, seasonal unemployment occurs when there is a lack of agricultural work during certain seasons, leading to temporary unemployment for agricultural workers.

It is important to address these types of unemployment in the agriculture sector to improve productivity and provide alternative employment opportunities. Policies such as promoting skill development, encouraging diversification of agricultural activities, and creating non-agricultural employment opportunities can help reduce unemployment in the sector and improve overall economic growth and development.
