Final answer:
D. Activities from the Activity Log in the past 90 days cannot be used to filter data for Smart Lists.
Step-by-step explanation:
The correct answer is D. Activities from the Activity Log in the past 90 days. Smart Lists allow you to filter data based on certain criteria, but you cannot filter by activities from the Activity Log. Filtering by membership in a program (option A), fields on a lead record (option B), and the number of unique web page visits (option C) are all possible methods of filtering data for Smart Lists.
