Which of the following is NOT a main type of insurance coverage?

Investment insurance is not a main type of insurance coverage. The primary types of insurance typically include life, health, and liability insurance. Life insurance provides financial protection to beneficiaries upon the policyholder's death, ensuring that loved ones are supported financially. Health insurance covers medical expenses and can help alleviate the financial burden of healthcare costs.

Liability insurance protects individuals and businesses from legal claims due to injuries or damages to other people or property. This type of coverage is essential for managing risk in various situations.

In contrast, while there are investment products that may resemble ‘insurance’ in some respects, such as certain types of annuities or investment-linked policies, they do not fit the conventional definition of insurance coverage. These products primarily serve investment purposes rather than providing risk management against loss in specific situations like those covered by the more recognized types. Thus, investment insurance does not belong in the same category as the other options listed.
