Answer:
C. a result of the seasonal pattern of work in specific industries
Step-by-step explanation:
Seasonal Unemployment results out of seasonal demand of labor in those industries where the nature of job is dependent upon weather or business seasons.
For example in case of crops, during the harvest season, there is high demand for labor while during the rest of the year there is no demand at all. So laborers of such industries are employed for a fixed duration in an year and remain unemployed for the rest of the period.
This unemployment is not due to inadequacy of labor skills but results owing to nature of the industry and seasonal pattern of the work required.
