A 'session' in Google Analytics is defined as a group of interactions (or events) that a user takes within a specific time frame on your website. This means that once a user arrives at your site, any actions—such as pageviews, events, transactions, and social interactions—are counted as part of that single session until either they leave the site or a predefined time limit (default is 30 minutes of inactivity) is reached.

This definition is crucial for understanding user behavior and measuring performance across various channels. It captures the complete journey of a user during that visit, which is invaluable for analyzing engagement and conversion metrics.

In contrast, focusing solely on a single user or a user's first visit does not encapsulate the dynamic nature of user interactions over time, making option A and option D inadequate. Option C, while closely related, is not specific enough since it implies that any interaction at any time is a session, which isn’t aligned with the time-bound definition of a session in Google Analytics. Therefore, the definition that best aligns with how Google Analytics categorizes a session is the grouping of events executed by a user within a specified time frame.
