Answer:
Answer is Option A: Affinity
Step-by-step explanation:
If one wants to search for the audience that aligns with their product, one must choose the affinity method. With this method, large amount of data can be gathered and organised into groups based on the criteria. It picks people's preferences based on online browsing and then organizes them based on their interests. Similar interests people will be grouped together and they are presented the data they are interested in. This method is also called “Space Saturate and Group”.
So, if one wants to re-engage with people from the database who bought something from the website in the past 6 months, affinity method will be used.
