The answer B is correct.
The answer C applies only on the MDC Table (Multi-Dimensional Clustering). Block Indexes are created with one or several table's dimensions and will reference several data blocks (block=extents) of the table. Each block will group data by dimension.
The answer D applies only on the RCT Table (Range Clustered Table). Indeed, its RID is computed by a key sequence (with one or several table's columns), the RCT table is clustered by default.
