Which of the following is true regarding Delaware’s licensing requirements?

In Delaware, the requirement that marketers of properties for sale or lease must hold a license is a fundamental aspect of the state's real estate regulations. This means that individuals or entities engaged in promoting, marketing, or showing properties to potential buyers or tenants are required to have the appropriate real estate license issued by the state. This licensing requirement helps ensure that marketers are knowledgeable about the real estate laws and practices, which protects consumers and promotes professionalism within the industry.

In contrast, the other scenarios presented often do not necessitate a license under Delaware law. For example, individuals acting under a power of attorney typically do not require a license, as they are acting on behalf of someone else in a legal capacity rather than engaging in real estate activities for profit. Companies managing their own properties may not need a license if they are not engaging in activities defined as real estate brokerage. Similarly, employees performing duties solely for their employer that do not involve soliciting buyers or tenants directly may also be exempt from the licensing requirement. Thus, option B stands out as the correct assertion about Delaware's licensing requirements.
