Final answer:
The complete list of types of real estate licenses in Delaware are Salesperson, Broker, Appraiser, and Property Manager, making Option 3 the correct choice.
Step-by-step explanation:
The types of real estate licenses in Delaware include Salesperson, Broker, Appraiser, and Property Manager. Therefore, Option 3 is the correct answer. In Delaware, separate licensing is required for these professions: real estate salespersons and brokers handle the buying, selling, and leasing of real estate; appraisers assess the value of properties; and property managers oversee the operation of real estate properties. Home inspectors also play a role in the real estate industry, but they are typically licensed under different regulations and their license is not considered a 'type' of real estate license.
