Which of the following structures does Liferay primarily aim to enhance through theme templates?

Liferay primarily aims to enhance UI consistency through theme templates. Theme templates are essential components in Liferay that allow developers to create uniform layouts and visual styles across different pages and applications within the platform. By utilizing templates, organizations can ensure that their user interface maintains a cohesive look and feel, regardless of the various functionalities provided by different portlets or applications.

This emphasis on UI consistency is vital for improving user experience, as it allows users to interact with the system seamlessly, without facing abrupt changes in design or usability across different sections. When users encounter an interface that is consistent in design elements, navigation, and overall layout, it increases their comfort level and satisfaction while using the platform.

While content delivery, database efficiency, and user analytics are important aspects of a web platform, they do not specifically relate to the primary purpose of theme templates in Liferay. Instead, theme templates are centered around ensuring that all visual aspects of the platform align cohesively, making option B the most relevant choice in this context.
