Answer: C

Explanation:

Pandas API on Spark (previously known as Koalas) provides a pandas-like API on top of Apache Spark.

It allows users to perform pandas operations on large datasets using Spark’s distributed compute capabilities. Internally, it uses Spark DataFrames and adds metadata that facilitates handling operations in a pandas-like manner, ensuring compatibility and leveraging Spark’s performance and scalability.
