A. Spark DataFrames do not directly support containing other DataFrames as columns. A DataFrame column can only have one of the supported data types, such as primitive types (e.g., IntegerType, StringType, DoubleType, etc.) or complex types (e.g., ArrayType, MapType, StructType, etc.), but it cannot contain an entire DataFrame as a column.

Selected Answer: A
Spark DataFrames are designed to store structured data, where each column has a specific data type. While DataFrames can contain various data types such as strings (option B), arrays (option C), null values (option D), and vectors (option E), they cannot directly contain other DataFrames (option A) as a column.
