An interactive space is a common space between entities. It offers scope for communication between those entities. In the figure below, each circular figure represents the plan of a house with a door opening. There are additional walls in some clusters. The house does not have windows. Five clusters (1, 2, 3, 4 and 5) of such houses are shown below.
If the clusters are arranged in an ascending order (lowest to highest) based on their potential for interactivity and communication within the cluster, which option is correct?
