Which of the following best defines the term 'grantor'?

The term 'grantor' specifically refers to the individual or entity that transfers ownership of a property to another party, typically through a legal deed. This is commonly seen in real estate transactions where a grantor is the seller who conveys the interest in the property to the buyer, also known as the grantee. The grantor is responsible for executing the necessary documents that formalize this transfer of ownership.

Understanding this definition clarifies the roles in a real estate transaction. The grantor's primary role is to relinquish their rights to the property, while the grantee is the recipient of those rights. Other roles mentioned in the question, such as providing funding or maintaining the property, do not align with the fundamental duties or definitions associated with a grantor. Therefore, option B accurately captures the essence of what a grantor is within the context of real estate transactions.
