Which of the following is a category of working alone?

The correct answer highlights a scenario where individuals may find themselves working alone, particularly in situations where they handle cash. In jobs such as retail or taxi services, employees often operate independently, especially when managing financial transactions. This can create unique safety considerations since being alone increases vulnerability to various risks, including theft or emergency situations, where immediate assistance might not be available.

The other options describe conditions that tend to mitigate the risks associated with working alone. Working in pairs for safety enhances security and can provide immediate support in case of an emergency. Always interacting with customers implies a continuous presence of others and usually suggests that the individual is not working alone. Similarly, performing tasks only in a team indicates a collaborative environment where individuals are not isolated, thereby minimizing the risks associated with solitary work. Understanding these contexts helps in identifying and managing the risks involved in working alone effectively.
