Why does clustering improve query performance in partitioned dbt tables?

ABecause clustering sorts data within partitions, reducing scan size

BBecause clustering compresses data to reduce I/O

CBecause clustering encrypts data for faster access

DBecause clustering duplicates data for redundancy

Step-by-Step Solution

Solution:

Step 1: Understand clustering effect on data layout
Clustering sorts data inside each partition, grouping similar rows together.
Step 2: Explain how sorting reduces query cost
Sorted data allows queries to scan fewer rows, improving speed and reducing resource use.
Final Answer:
Because clustering sorts data within partitions, reducing scan size -> Option A
