The correct answer is B. High unemployment led to a lot of theft and robbery
Explanation
Crime can be related to immigration as migrants, especially illegal migrants might not fill with the requirements to apply to legal jobs or might find difficult to get legal jobs due to discrimination or differences in qualifications from their origin county and the country to which they migrate; due to the high unemployment migrants experience and the lack of economic support from other sources, many migrants might choose robbery or theft as an alternative to get the money they require to pay for food and other basic needs. On the other hand, migration does not imply necessarily conflicts between different ethnic or religious groups or rising gang activity.
