Final answer:
Dylan and Bob should purchase Key person disability insurance to safeguard their business in case their star salesman becomes disabled, as it offers financial assistance tailored for businesses losing a critical team member.
Step-by-step explanation:
Dylan and Bob, who own a small business, are concerned about the impact on their company if their star salesman were to become disabled. The type of policy that would best address this concern is Key person disability insurance. This insurance is specifically designed to provide financial assistance to a business in the event that a crucial member of the team, often one whose role is critical to the company's profitability, is unable to work due to a disability. By contrast, Business overhead expense disability insurance would help cover ongoing business expenses, Individual disability insurance is intended for the salesperson's own income replacement, and Group disability insurance provides coverage for all employees rather than targeting a key individual.
