Which of the following is an advantage of a large deductible plan?

A large deductible plan provides cash flow incentives primarily because it allows individuals or businesses to lower their monthly premium payments in exchange for taking on a higher financial risk when it comes to out-of-pocket costs for covered services. This setup can lead to significant savings on premiums, which can be particularly beneficial for those who don't expect to incur many health care expenses.

By choosing a larger deductible, policyholders can retain more cash in hand on a monthly basis, which can be allocated towards other financial needs or investments. This incentivizes responsible spending on health care, as individuals become more mindful of the costs associated with their care.

The other options do not specifically address the core benefit of a large deductible plan. Compliance with federal regulations is often a requirement across different types of insurance but does not directly relate to the advantages of the plan's structure. Guaranteed returns on investments is typically not associated with health insurance, and while lower premiums are indeed a feature of large deductible plans, they are not necessarily guaranteed across different claims scenarios, as pricing can vary based on several factors, including the insurer and market trends.
