Insurance which covers business expenses and payroll when the insured businessowner is disabled is:

Workers compensation insurance provides coverage for employees who suffer job-related injuries or illnesses, covering their medical expenses and lost wages. However, it does not cover the business owner's personal expenses or payroll during their disability, making it unsuitable for this context.

Professional insurance typically refers to liability coverage for professionals against claims of negligence or malpractice in their services. While it protects the professional's business from legal claims, it does not address the issue of covering ongoing business expenses or payroll in the event of the owner's disability.

Special risk insurance provides coverage for unique or high-risk situations that are not typically covered by standard policies. While it may offer protection for particular risks, it does not specifically address the ongoing expenses and payroll needs of a business owner who is disabled.
