Selected Answer: C
C: The pandas API on Spark (pandas-on-Spark) provides a pandas-like interface for distributed data processing in Apache Spark. Internally, a pandas API on Spark DataFrame is built on top of a Spark DataFrame with additional metadata that allows it to mimic the pandas DataFrame interface. This design enables users to use familiar pandas syntax while leveraging Spark’s distributed computing capabilities
