What type of deed promises that the title is good and clear of claims?

The general warranty deed is the correct choice because it provides the highest level of assurance from the grantor to the grantee regarding the title of the property. This type of deed guarantees that the title is free and clear of any claims, liens, or encumbrances, and it includes specific covenants of title. These covenants typically include the covenant of seisin (the grantor has the right to convey the property), the covenant against encumbrances (the property is free from any encumbrances), and the covenant of quiet enjoyment (the grantee will not be disturbed in possession due to claims against the title).

In contrast, a quitclaim deed does not provide any warranties regarding the title and merely transfers whatever interest the grantor may have. A special warranty deed provides limited guarantees, only covering the period during which the grantor owned the property, and not for any claims that may have arisen before. A deed in trust typically involves creating a trust and entrusting the property to a trustee for the benefit of a beneficiary, and does not pertain to guarantees related to title assurance. Therefore, the general warranty deed's promise of a clear and good title makes it the correct answer in this scenario.
