Hi @Michael_Soprano ,
Let's break down the information based on each set of records,
1. First 20 records Primary ID - A1 : This creates a new profile fragment as A1 is introduced for the first time
2. Next 20 records P.I - A2, S.I - B2 : This creates a new profile fragment as A2 is introduced for the first time
3. Next 20 records P.I - A1, S.I - B2 :These records don’t create a new profile fragment; instead, they merge with the existing profile fragment of A1, because A1 was already introduced.
4. Last 20 records P.I - A2,S.I - B2:These records don’t create a new profile fragment; instead, they merge with the existing profile fragment of A2, because A2 was already introduced.
Therefore, there are 2 new and 78 existing profile fragments out of 80.
Hence, as per the above explanation, option A should be the correct answer.
