Vertical fragmentation refers to dividing a relation into vertical subsets, where each subset contains specific attributes or columns. This fragmentation can be useful in situations where different subsets of data are needed or used by different applications. Horizontal fragmentation refers to dividing a relation into horizontal subsets, where each subset contains specific rows of data. Data fragmentation is a more general term encompassing both vertical and horizontal fragmentation. Mixed fragmentation involves using both vertical and horizontal fragmentation techniques to divide a relation. However, none of the choices accurately describe "attribute subsets" except for C) Vertical fragmentation.
