In the question given below there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.

Assertion (A)- At a later stage of development, workers migrate from rural areas to urban areas in search of job.

Reason (R)- In the course of economic development of a country, labour flows from agriculture and other related activities to industry and services and these are predominantly available in urban areas.

Both (A) and (R) are true and (R) is the correct explanation.

In the course of economic development of a country, labour flows from agriculture and other related activities to industry and services. In this process, workers migrate from rural to urban areas. Eventually, at a much later stage, the industrial sector begins to lose its share of total employment as the service sector enters a period of rapid expansion. This process of development is mostly witnessed by all the developed countries of the world.
