Frictional unemployment a) is present even when labor markets are working well. b) is the result of worker skills not matching the jobs available. c) is zero when the economy achieved the natural rate of unemployment. d) exists only when the economy is in the natural rate of unemployment.

The correct answer is A) is present even when labor markets are working well.

Explanation:

In the economy, frictional unemployment is caused by workers or individuals moving from job to another, this occurs because the individual moves to a new place, he or she leaves his/her current job to find a better one or looks for a job that fits new skills, experience or education. Due to this, this type of unemployment does not relate to the development of the economy but voluntary transitions in the life and job of individuals. As a result, frictional unemployment occurs naturally even in stable or growing markets (Option A).
