A. Spark DataFrames are the same as a data frame in Python or R.: This statement is incorrect because Spark DataFrames, while conceptually similar to data frames in Python (e.g., pandas) or R, are not the same. Spark DataFrames are distributed, immutable, and built on top of RDDs, designed to handle large-scale data processing across a cluster. In contrast, data frames in Python (pandas) or R are typically in-memory, single-node constructs.
