The majority of in-migrants to Kerala work in:

Skilled professions
Agriculture
Unskilled labor
Tourism Answer: c

The majority of in-migrants to Kerala work in unskilled labor. This is because Kerala has a large number of low-paying jobs in the service sector, such as construction, domestic work, and tourism. These jobs are often filled by in-migrants from other parts of India who are looking for better opportunities.

Skilled professions are less common in Kerala, as the state has a relatively small number of high-paying jobs in these fields. Agriculture is also not a major source of employment for in-migrants, as Kerala has a relatively small agricultural sector. Tourism is a growing industry in Kerala, but it does not provide enough jobs to meet the demand of in-migrants.

In conclusion, the majority of in-migrants to Kerala work in unskilled labor. This is because Kerala has a large number of low-paying jobs in the service sector, such as construction, domestic work, and tourism. These jobs are often filled by in-migrants from other parts of India who are looking for better opportunities.
