Final answer:
Option a. An employee was injured during a lunch break in the factory parking lot.
Step-by-step explanation:
In the context of workers' compensation, the phrase 'arise out of and in the course of employment' refers to injuries that occur while an employee is performing their job duties or engaging in activities that are directly related to their employment. Based on this definition, option a would NOT be considered an injury that arises out of and in the course of employment. This is because a lunch break is typically considered a personal activity and not directly related to job duties.
