Final answer:
The statement that is NOT true about analytics segments is that segments are filters that permanently change your data. Segments apply filters that temporarily alter the view of the data without changing the raw data itself.
Step-by-step explanation:
Segments in analytics are subsets of data that allow for more granular analysis, and one of the statements about segments in the question is not true. To address the multiple-choice question:
a. Segments are filters that permanently change your data. This is the statement that is NOT true about analytics segments. The correct notion is that segments temporarily change data for analysis without altering the underlying data.
b. Segents let you isolate and analyze your data. This is correct; segments filter data to help identify patterns or trends within a specific subset of analytics data.
c. You can use segments to build custom Remarketing lists. This is also true as segments can be used for targeting specific users based on their behavior.
d. Segments represent either subsets of sessions or subsets of users. This is true as segments can be defined as a group of users who have something in common or specific interactions within a session.
