When selecting 'Title Only' for Cluster metrics, what is displayed?

Selecting 'Title Only' for Cluster metrics displays the title of the cluster, which typically includes a summary representation of the cluster’s content. This title is usually derived from the most prominent terms or keywords associated with the documents grouped within that cluster, providing a concise indication of its overarching theme or topic.

In this context, option D is the correct interpretation of what 'Title Only' signifies, as you will see a title for the cluster that summarizes its main focus with up to ten key terms. This simplified view allows for quicker identification and analysis of clusters in relation to the data being evaluated, enabling users to understand the clusters' themes without delving into the details of each document.

The other options, while pertinent to the overall understanding of cluster metrics, do not accurately describe what is displayed when 'Title Only' is selected. The assigned number of the cluster, number of documents, and coherence metrics serve different analytical purposes and insights, rather than presenting the cluster title itself.
