Answer:
d. Lumber Needs is vicariously Liable because Cassie was acting within the course of employment
Step-by-step explanation:
Vicarious Liability
Vicarious Liability is a third party responsible liability. Someone else is liable for another's actions or errors. This liability is usually because the one originally liable has been proven to be working within the course of agreement of the third part as at the time the liability occurred.
This type of liability is usually taken in the workplace, where an employee working within the context of his/her working condition or agreement with the employer commits a liability. As such the employer is liable for the act.
Cassie was demonstrating a power saw as a salesperson of Lumber needs, therefore, she was working within the context of her agreement with Lumber needs.
