The cause of migration that is an example of a pull factor is C. job availability.

A pull factor in the context of migration refers to factors that attract or draw people to a particular location. Among the given options, "C. job availability" is an example of a pull factor.

To determine the answer, you can start by understanding the definitions of each option.

Warfare (option A) refers to armed conflicts or wars within a region, which often compels people to leave their homes due to safety concerns. This is considered a push factor, as it drives people away from the impacted area.

Poverty (option B) refers to the lack of resources, opportunities, and economic stability, which can compel individuals to seek better living conditions elsewhere. Like warfare, poverty is considered a push factor.

Job availability (option C) refers to the presence of job opportunities and employment prospects in a specific location. This factor attracts individuals searching for work and economic stability, making it an example of a pull factor.

An earthquake (option D) typically causes immediate damage to infrastructure and can displace people. However, as it is a sudden and often temporary event, it is not primarily considered a pull factor or a push factor.

Therefore, the correct answer is C. job availability.
