Final answer:
The marketer would use Advanced filters to pull a list of leads that changed status to MQL in the last 30 days, as Advanced filters allow for segmentation based on specific criteria and timeframes.
Step-by-step explanation:
A marketer who needs to pull a list of leads whose lead status changed to MQL (Marketing Qualified Lead) in the last 30 days would likely need to use Advanced filters. Advanced filters in CRM or marketing automation platforms allow users to sort and segment leads based on specific criteria, such as changes in lead status within a set timeframe.
The other options, Add choice and Cached list, do not specifically relate to filtering by time-based changes, and Add constraint typically refers to narrowing down a list based on specific criteria but does not itself retrieve time-based data.
