Explanation:
The correct answer highlights the fundamental difference between Z-ordering and bin-packing optimizations. Z-ordering is concerned with the number of rows to achieve uniform file sizes, whereas bin-packing looks at the actual size of files on disk. This distinction is crucial for understanding how each method optimizes data storage and retrieval efficiency.

What distinguishes Z-ordering from bin-packing in terms of optimization goals?
A
Both bin-packing and Z-ordering optimization techniques aim to create files of similar size based on their size on disk.
B
Z-ordering optimization focuses on creating files of similar size based on the number of rows, while bin-packing optimization targets similar file sizes based on their disk size.
C
Bin-packing optimization aims for similar-size files based on the number of rows, whereas Z-ordering optimization does so based on the number of columns.
D
Both techniques strive to achieve files of similar size based on the number of rows.
E
Z-ordering optimization attempts to create files of similar size based on their disk size, while bin-packing optimization focuses on the number of rows.
