Answer:
Institutional
Step-by-step explanation:
Institutional advertising is that which promotes the ideas, vision, mission, or philosophy of an institution, businesses, or organization, instead of promoting their products or services. It is often used to build a reputation for the institution and inform the consumers about it is or what it does. So, when Congressional Realty advertises all of its listed properties, it is trying to create an image for itself, it is using institutional advertising.
