The primary cause of **frictional unemployment** is: **(1) Inaccurate and costly information about job opportunities.** ### Explanation: Frictional unemployment occurs when individuals are temporarily between jobs or are entering the labor force for the first time. This type of unemployment is primarily caused by the time and effort required to match workers with suitable job opportunities. - **Inaccurate and costly information about job opportunities** (Option 1) makes it difficult for job seekers to find the right positions efficiently, leading to increased frictional unemployment. **Other Options:** - **(3) Discouraged workers who give up looking for work** typically relate to **structural** or **cyclical unemployment**, not frictional. - **(4) The lack of training and marketable qualifications in job seekers** is also associated with **structural unemployment**, where there's a mismatch between workers' skills and the needs of employers. Therefore, **Option (1)** is the most accurate answer regarding the primary cause of frictional unemployment.
