Which of the following services requires an individual to be licensed in real estate?

An individual must be licensed in real estate to perform activities that involve negotiating or facilitating transactions in real property. This includes brokering sales, managing properties, engaging in rental activities, and appraising real estate. Each of these services requires a specific level of expertise and adherence to legal standards, which is why licensing is mandated.

Brokering transactions involves acting as an intermediary in the sale, purchase, or lease of property, which is core to what a real estate broker does. Managing property not only requires knowledge about property laws and landlord-tenant relationships but also often involves financial management, making it essential for property managers to be licensed. Rental activities also fall under the umbrella of property management and require a license when the activities involve negotiation or management of rental agreements.

Appraising is also a regulated activity typically requiring a license, as appraisers assess property values for determining sale conditions or securing financing, which involves ensuring compliance with market standards and regulations.

While managing property on its own or simply appraising and counseling might seem to narrow the scope, the comprehensive nature of the required services in option D encapsulates all the necessary licensed activities within real estate, making it the most accurate choice.
