Why does query performance decrease when the data volume of the delta storage is large in SAP HANA?

a) Because the delta storage is designed for temporary data storage and becomes overloaded with excessive data volume.
b) Because accessing and processing large volumes of data in the delta storage requires more computing resources and slows down query performance.
c) Because the delta storage lacks efficient indexing and data organization mechanisms, leading to slower data retrieval.
d) Because the delta storage is not optimized for handling large data volumes, resulting in longer query execution times.
