Which type of insurance is designed to protect against errors and omissions in professional services?

The correct type of insurance designed to protect against errors and omissions in professional services is often referred to as Errors and Omissions (E&O) insurance, which falls under the broader category of professional liability insurance. It specifically covers professionals, such as consultants, doctors, attorneys, and accountants, from claims of negligence, mistakes, or inadequate work in the services they provide.

Casualty insurance, while related to risk management and liability, mainly deals with losses that occur due to accidents, theft, and damage to property. This type does not specifically focus on the professional liabilities that arise from errors and omissions in services provided, making it less applicable to the context of professional service protection.

On the other hand, health insurance primarily covers medical expenses, life insurance provides financial protection upon the death of the insured, and annuities are financial products that provide income during retirement. None of these options directly relate to errors and omissions in a professional context. Therefore, the focus on protecting professionals from claims arising from their services highlights why the correct answer is categorized under casualty insurance, as it encompasses the necessary elements to shield against such risks.
