Final answer:
A commercial policy with only one coverage form is known as a monoline policy, providing specific coverage without additional complexities.
Step-by-step explanation:
A commercial policy that has only one coverage form is typically referred to as a monoline policy. This kind of policy differs from a package policy, which combines multiple forms of coverages such as property and liability.
Monoline policies are sought for their simplicity and for situations where only a specific type of coverage is needed, without the added complexity or cost of additional coverages that may not be necessary for the insured's situation. For instance, a business might purchase a monoline workers' compensation policy if it only needs to cover employee-related injury risks without additional property or liability coverages.
